Best Drywall Anchors for Plaster: What Works and How to Choose
Yes, drywall anchors can work in plaster, but the right type depends on the wall’s construction and the weight of the item. Choose an anchor specifically listed for plaster, and use extra care because plaster can crack around a hole. The JoblikeBrez molly bolt kit is best for hollow walls and heavier fixtures; FixMaster zinc self-drilling anchors are better for quick installation; and Hillman’s dual-action anchors suit buyers who want one anchor type for solid or hollow surfaces.

| FixMaster Zinc Anchors | Fast installation in plasterboard | Listed thicknesses: 3/8, 1/2, and 5/8 in; up to 75 lb |
| Hillman Dual-Action Nylon Anchors | Mixed wall materials | Plaster, drywall, masonry, and more |

JoblikeBrez Molly Bolts For Hollow Plaster Walls
These metal molly bolts are the clearest match for hollow plaster walls among the listed options. Their expansion arms open behind the wall surface, and the kit includes a setting tool. The stated wall thickness range is 0.12 to 1.28 inches, and the listing says they are suitable for hollow plaster, drywall, gypsum fiberboard, and other panel materials.
Best for: People hanging mirrors, curtain rods, towel racks, or similar fixtures on a hollow wall who want a mechanically expanding anchor. The listing states a capacity of up to 55 pounds; actual safe capacity depends on the wall and installation. Limitation: Installation requires drilling a hole and using the included setting tool, so this is not the quickest no-pilot-hole option.
FixMaster Zinc Self-Drilling Anchors
This kit includes 50 zinc anchors and 50 carbon-steel screws. The manufacturer describes the anchors as self-drilling for drywall or plasterboard and says no pilot hole is required. Their deep threads are intended for 3/8-, 1/2-, or 5/8-inch wallboard. The listed holding strength is up to 75 pounds.
Best for: Buyers who need a large supply of anchors and want a fast installation in plasterboard within the listed thickness range. Limitation: The stated wall types and thicknesses are specific. Confirm that the wall matches before choosing this style, and do not treat the advertised capacity as a guarantee for every plaster wall or installation.
Hillman Dual-Action Nylon Wall Anchors
Hillman’s nylon anchor is designed to work in hollow and solid materials. In hollow walls, it folds and knots behind the surface; in solid materials, it expands along the screw. The listing recommends it for plaster, drywall, tile, block, brick, and concrete. Installation calls for a pre-drilled hole at least twice the anchor’s length.
Best for: Households dealing with different wall materials and wanting a single anchor style for several mounting jobs. Anti-rotation fins are intended to help keep the anchor from spinning. Limitation: It requires a drilled hole, and the provided product details do not state a load capacity. Select it based on the application and wall condition rather than assuming a particular weight rating.
TriLnno Self-Drilling Metal Anchors
These carbon-steel anchors have a yellow-zinc coating, and the listing says they install without pre-drilling. They are described for drywall, gypsum board, hollow brick, and several lightweight board materials. The stated capacity is up to 80 pounds per anchor, and the 20-piece kit is intended for mounting items such as frames, shelves, or lights.
Best for: Buyers seeking metal self-drilling anchors for a listed board material and a straightforward installation. Limitation: The product information does not specify a plaster-wall thickness range. Its capacity claim should not be assumed for old, brittle, cracked, or unknown plaster construction.
Hillman Dual-Material Anchors With Screws
This 18-pack uses two nylon components that expand differently depending on the base material. The listing includes plaster, drywall, tile, concrete, brick, and block among its intended applications. Matching Phillips pan-head screws are included, and the anchor accepts screw sizes 6 through 10. Installation is specified with a 1/4-inch drill bit.
Best for: Small household mounting projects where the wall material may vary and included screws are useful. Limitation: The provided details do not give a holding capacity, so it is not possible to compare its rated load with the products that state one.
Buying Guide: How To Choose An Anchor For Plaster
Is the plaster wall hollow or solid?
Plaster may cover lath or another backing, and wall construction can vary. In a hollow wall, an expanding molly bolt or a suitable folding anchor can grip behind the surface. A solid base calls for an anchor designed to expand or grip in that material. Identify the wall structure before selecting hardware.
Should you use a self-drilling anchor?
Self-drilling models save a separate pilot-hole step, but plaster can be brittle. If drilling or driving causes cracking, stop and reassess rather than forcing the anchor. For a delicate or uncertain wall, a drilled installation with an anchor suited to the wall may offer more control.
How much weight will the anchor hold?
Use a product’s stated capacity only as a starting point. The listed ratings apply to specified materials and installation conditions; plaster condition, wall thickness, anchor spacing, and the direction of force can affect performance. For heavy or safety-critical items, fastening into a stud or other structural support is generally preferable when available.
What should you check before installation?
- Confirm that the product specifically lists plaster or the exact wallboard type.
- Check the wall thickness range and required hole size or drill bit.
- Inspect for loose, cracked, or crumbling plaster around the mounting point.
- Use the supplied screw size and follow the anchor’s installation instructions.
Frequently Asked Questions
Will drywall anchors work in plaster?
Some will. Choose an anchor whose product information specifically includes plaster or the relevant plasterboard type; not every drywall anchor is intended for every plaster wall.
Are molly bolts suitable for plaster?
Molly bolts can suit hollow plaster walls when the wall thickness matches the anchor’s range and the installation is done as directed. They expand behind the wall to create a hold.
Can self-drilling anchors be used in plaster?
Some products are listed for plasterboard or plaster, but suitability depends on the exact wall construction. Follow the stated wall type and thickness, and avoid forcing an anchor if the plaster cracks.
Should I use an anchor or find a stud?
For heavy or safety-critical items, a stud or structural support is generally the stronger choice when accessible. Anchors are useful when mounting in a hollow area, but their performance depends on the wall and installation.
Does a listed weight capacity guarantee a safe hold?
No. A listed capacity is not a universal guarantee. The wall material, condition, installation, and load direction can change how well an anchor holds.
