Standard plastic anchors strip out, spin, and fail under real loads — especially in hollow walls where there's nothing solid to bite into. Molly bolts solve this by expanding behind the wall surface, distributing the load across a wide flange that grips from the inside out. This kit gives you the right anchor for the job, every time.
The kit includes a carbon steel setting plier and 40 molly bolts in 8 sizes — M4×32mm, M4×46mm, M4×60mm, M5×37mm, M5×52mm, M5×65mm, M6×37mm, and M6×52mm (5 pcs each). The ergonomic non-slip grip plier compresses the anchor precisely, expanding it firmly against the back of the wall without over-driving or damaging the surface.
Designed for drywall, hollow block, plaster, and tile — use it to hang curtain rods, shelves, photo frames, coat racks, lamps, towel bars, and power switch plates. A single kit covers the most common hollow-wall fastening tasks around the home.

A molly bolt (also called a hollow wall anchor) expands behind the wall surface when set, creating a wide flange that grips from the inside. Unlike plastic expansion anchors that grip within the wall material, molly bolts distribute load across a larger area — making them significantly stronger in hollow walls.
Yes. You need to drill a pilot hole sized to the anchor diameter before inserting the molly bolt. Once the anchor is in place, use the included setting plier to expand it against the back of the wall. A standard power drill or hand drill is sufficient.
Match the thread size (M4, M5, or M6) to the screw or bolt you plan to use for your fixture. Choose the anchor length based on your wall thickness — the anchor body should be long enough to pass through the wall and expand fully behind it. When in doubt, use a longer anchor.
Load capacity varies by anchor size and wall material. Larger sizes (M6) generally support more weight than smaller ones (M4). In 1/2" drywall, molly bolts typically support 30–50 lbs per anchor when properly installed. Always distribute heavy loads across multiple anchors.
Yes. These molly bolts are suitable for drywall, hollow block, plaster, and tile. For tile, use a tile drill bit to create the pilot hole carefully before inserting the anchor. Avoid cracking the tile by drilling at low speed without hammer mode.
Molly bolts are generally considered permanent fasteners once set — the expanded flange locks behind the wall. To remove, you can back out the screw and push the anchor body into the wall cavity, then patch the hole with drywall compound. Alternatively, use a screw extractor if the anchor needs to be fully removed.
Yes. The carbon steel setting plier is a reusable tool designed to work with M4, M5, and M6 molly bolts. It can be used repeatedly across all 40 anchors in this kit and for future anchor installations.
