Driving a standard wall anchor into old lath and plaster feels like a coin flip — either it crumbles the surrounding material or the screw spins uselessly in a hollow cavity behind the face. The difference between a secure mount and a gaping hole comes down to one thing: the anchor’s ability to mechanically grab the backside without relying on the brittle plaster for compressive strength.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. For this guide, I’ve analyzed over four hundred customer reports and spec sheets on hollow-wall fasteners, focusing exclusively on how each design handles the unique gap-and-crumble problem of lath-and-plaster construction, so you can mount shelves, mirrors, and TVs without retching.
Molly bolts that expand a metal sleeve against the back of the wall are the only reliable method for lath and plaster because they transfer load to the lath strips, not the brittle surface. Read on for a carefully curated list of the best anchors for lath and plaster walls, tested through real-world owner feedback and matched to different project scales.
How To Choose The Best Anchors For Lath And Plaster Walls
Lath and plaster walls differ fundamentally from modern drywall. The plaster face is brittle and typically ⅜” to ¾” thick, with an irregular air gap behind it before the wooden lath strips begin. A standard plastic expansion anchor pushes outward against the edge of the hole, which often chips or cracks the plaster before the anchor can grip. You need a fastener that passes through the plaster and gap, then expands its wings or sleeve against the lath or the backside of the wall cavity.
Anchor Type — Molly Bolts vs Toggle Bolts vs Sleeve Anchors
Molly bolts are the safest choice for lath and plaster. Their collapsible metal sleeve is inserted into a drilled hole, then the screw is tightened to crush the sleeve outward against the wall cavity’s backside. Unlike toggle bolts (which require a large hole to insert the spring-loaded wing), molly bolts leave a smaller entry wound and can be removed while leaving the expanded sleeve in place, preserving the hole for future use. Sleeve anchors meant for masonry should not be used — they rely on uniform density that plaster alone cannot provide.
Sleeve Length — Must Exceed Plaster Thickness
The anchor’s sleeve or expansion section must be long enough to clear the plaster layer and the air gap before it opens. Most quality kits specify compatibility with wall thicknesses of 0.12″ to 1.28″, which covers nearly all residential lath-and-plaster assemblies. If the sleeve is too short, the wings expand inside the plaster itself, causing a blowout. Measure your wall assembly with a bent wire or thin probe before buying any kit.
Setting Tool — Reduces Plaster Damage Risk
A dedicated molly bolt setting tool uses a scissor or lever action to pull the screw head outward while bracing against the wall face, collapsing the sleeve without twisting torque on the plaster. Standard screwdriver installation tends to spin the anchor body relative to the plaster, abrading the hole edge and weakening the grip. Kits that bundle a tool with multiple anchor sizes typically deliver more consistent results on older walls.

In‑Depth Reviews
1. AKKTOL Molly Bolts for Drywall & Plaster Walls — 36 PCS
The AKKTOL kit lands as the top contender because it delivers the widest size selection — six distinct anchor diameters and lengths — paired with a heat-treated carbon steel setting tool that owners consistently describe as durable even after setting over a hundred anchors. The 2.5mm thickened steel of the pliers head resists the spreading fatigue that thinner tools develop after repeated expansion cycles, which matters when you’re working through multiple holes in a single plaster wall project.
Each anchor in this set carries a holding range of 40 to 65 pounds, and the zinc-plated carbon steel construction resists corrosion well enough for indoor and sheltered outdoor use. The inclusion of a double-sided storage box is a practical bonus — keeping the six sizes organized prevents the frustrating search for the right anchor mid-install. Owners praised the tool’s ergonomic non-slip grip for reducing hand fatigue during repetitive expansions.
The only notable shortcoming is that some users found the included molly bolts to be softer than expected, with a few units collapsing too easily when squeezed by hand. The kit also lacks a reference chart for the precise drill bit size for each anchor, though the manufacturer has added that information after initial customer complaints. For heavy loads on delicate plaster, this is the most versatile and confidence-inspiring set available.
What works
- Six anchor sizes cover a wide range of plaster thicknesses and loads
- Thickened tool steel withstands high-volume installation without deforming
- Ergonomic grip reduces fatigue during multi-anchor projects
- Storage box keeps the set organized and portable
What doesn’t
- Some anchor bodies are softer than ideal and may deform under heavy torque
- No drill-bit size guide included with the initial kit
- Metric thread anchors may not mate with standard US screws
2. LIBRATON Molly Bolts for Drywall & Plaster Walls — 30 PCS
The LIBRATON kit stands apart because it accommodates the thickest plaster assemblies of any set in this roundup — its sleeve compatibility extends to 1.52 inches, covering walls where the plaster plus air gap surpasses the standard 1.28-inch limit. The setting tool uses a lightweight aluminum body paired with an A3 steel impact head, and the lever-action design expands anchors with a single squeeze rather than requiring the hammer-and-pull sequence that can crack brittle surfaces.
With a 65-pound holding capacity and six sizes included, this kit covers essentially every hollow-wall scenario from light picture frames to heavier shelf brackets. The 360° swivel expansion mechanism is specifically engineered to distribute force evenly around the hole, which reduces the risk of radial cracks propagating through aged plaster. Owners report that the tool installs molly bolts significantly faster than manual hammer-and-screwdriver methods.
On the downside, the hardware quality has drawn sharp criticism from a small but vocal group of users who experienced anchors breaking apart inside the wall cavity. One handy owner with extensive molly bolt experience reported that the included fasteners were the lowest-quality he had encountered and returned the set. The tool itself works well, but the inconsistent anchor metal means you may want to pair this kit with separately purchased high-grade bolts for critical loads.
What works
- Handles plaster up to 1.52″ thick — best for deep wall assemblies
- Lightweight aluminum tool with fast lever-action expansion
- Pressure-dispersion design reduces plaster cracking during installation
- Six anchor sizes offer broad compatibility
What doesn’t
- Included anchor hardware can be brittle and may fail inside the wall
- Tool alone is excellent, but the anchor quality is inconsistent
- Not suitable as a single-buy solution if you need bulletproof fasteners
3. BURMONG Heavy Duty Molly Bolts for Drywall — 34 PCS
The BURMONG kit earns the Best Overall tag because it strikes the cleanest balance between anchor quality, tool durability, and straightforward installation for lath-and-plaster walls. The setting tool is built from one-inch hardened carbon steel, and owners consistently report that the 34-piece set includes exactly the three most useful sizes (M5x37mm, M5x52mm, M6x52mm) without the filler sizes that complicate organization. Each anchor is made from galvanized carbon steel with a plain finish that resists rust without adding thickness that could bind during insertion.
The unique expanding-arm design opens outward against the wall backing rather than relying on the plaster edge for purchase, which is exactly what lath-and-plaster applications demand. The internal thread structure allows screws to be removed and reinserted without compromising the anchor’s grip, a feature that matters when you reposition shelves or swap out hardware. With a load rating of 55 pounds per anchor on half-inch drywall or plaster, this kit comfortably handles TV mounts, heavy mirrors, and curtain rods.
Some users noted that the rubber grip on the setting tool slid off after a few uses, requiring a dab of glue to keep it in place — a minor annoyance rather than a functional failure. A handful of reviews also mention that the setting tool could feel slightly undersized for larger hands, though the core mechanics remained reliable. For the vast majority of residential plaster projects, this is the kit that arrives ready to work without surprises.
What works
- Hardened carbon steel tool resists wear over dozens of installations
- Three anchor sizes cover the most common lath-and-plaster depths
- Galvanized finish prevents rust without increasing anchor diameter
- Removable screw design allows adjustments after installation
What doesn’t
- Rubber grip on the setting tool can slide off with heavy use
- Tool handle may feel short for users with larger hands
- No storage case for the anchor assortment
4. JoblikeBrez Molly Bolts for Drywall Plaster Walls — 34 PCS
The JoblikeBrez kit mirrors the BURMONG set in its component count and anchor sizing but comes at a slightly higher price point while still representing strong value for a DIY homeowner. The butterfly-style plaster wall anchor uses the same expansion-arm principle that presses firmly against the back of the wall plate, and the internal thread design allows repeated screw removal without degrading the hold. Owners especially appreciated how well this kit handled mounting on plaster walls without accessible studs.
The setting tool is made from the same one-inch hardened carbon steel as the BURMONG, and the included user manual provides clear steps for the drill-and-expand process. The three anchor sizes cover the 0.12-to-1.28-inch wall thickness range that covers most residential plaster, and the galvanized carbon steel construction resists rust well enough for indoor use. Several reviewers noted that the tool eliminated the stripped-bolt frustration they had experienced with plastic anchors on older walls.
A small number of users felt the tool was heavy for its size, which could be a factor during extended overhead work. Additionally, while the anchors set firmly, the kit could benefit from a thicker range of screw lengths for very deep plaster-and-lath assemblies. For straightforward household tasks like towel racks, picture frames, and shelving brackets on normal plaster, this is a dependable and easy-to-use kit.
What works
- Easy drill-and-expand install that avoids plaster cracking
- Three anchor sizes fit standard wall thickness ranges
- Galvanized steel resists corrosion and holds 55 pounds per anchor
- Setting tool eliminates stripped-anchor frustration
What doesn’t
- Tool is somewhat heavy for extended overhead work
- Screw lengths could be longer for deep wall assemblies
- Lacks a storage case for anchor organization
5. MOWIS Molly Bolt Setting Tool — 30 PCS in 5 Sizes
The MOWIS kit offers the second-highest variety of anchor sizes in this lineup — five distinct dimensions with six anchors each — making it a strong choice for households that need to match multiple screw gauges to different mounting points. The setting tool is crafted from 2.5mm reinforced carbon steel that has undergone heat treatment, and the ergonomic non-slip grip design is comfortable enough for sustained use. The load range spans 40 to 65 pounds, giving flexibility for everything from lightweight clocks to medium-duty shelving.
The galvanized carbon steel anchors are suitable for both indoor and sheltered outdoor use, and the included 24-month quality guarantee from MOWIS adds a layer of confidence for buyers investing in a multi-year hardware kit. Owners transitioning from plastic anchors reported that the MOWIS tool made installation simple and produced a noticeably more solid, sturdy hold in plaster. The variety pack covers M4 through M6 threads, which accommodates most standard accessory screw sizes.
However, the tool’s groove for the screw head is slightly oversized — the washer must sit perfectly in the groove for the tool to grip effectively, which adds a small alignment step that some users found fiddly. More critically, owners with genuine plaster walls reported that the tool’s fastener grip felt slippery when working with the uneven surface of old plaster, and in some cases the tool added an irritating extra step without improving over the normal method. For drywall and newer plasterboard the MOWIS performs well, but traditional lath-and-plaster may expose the tool’s grip limitations.
What works
- Five anchor sizes provide broad threading compatibility
- Heat-treated carbon steel tool resists wear and corrosion
- 24-month quality guarantee backs the purchase
- Galvanized anchors work indoors and in dry outdoor locations
What doesn’t
- Tool groove requires precise washer alignment for grip
- Slippery grip on uneven plaster surfaces reduces effectiveness
- May not improve over manual method on genuine lath-and-plaster
Hardware & Specs Guide
Molly Bolt Sleeve Length
The sleeve — the collapsible metal tube that expands behind the wall — must be long enough to span the plaster face, the air gap, and the lath surface before opening. A sleeve that is too short expands inside the air gap or within the plaster itself, creating a bulge or crack. Most quality kits cover wall thicknesses from 0.12″ to 1.28″. For walls built before 1950, the plaster and lath assembly can reach 1.0″ or more, so the 1.28″ upper limit is usually adequate. If your probe indicates a thicker assembly, look for a kit rated to 1.52″ or separately purchase longer-shank molly bolts.
Tool Leverage & Jaw Design
The setting tool’s jaw opening and pivot leverage determine how easily you can collapse the anchor sleeve. Tools with a single-action scissor mechanism (squeeze once to expand) are faster than two-step hammer-and-pull tools. The jaw must clamp the screw head securely without slipping, which is why some owners prefer tools with a deep, grooved jaw that accommodates the washer. Thicker jaw steel (2.5mm vs 1.0mm) resists deformation over hundreds of cycles. Aluminum-body tools are lighter but may transfer less force, requiring a firmer grip.
