Molly fastener

A molly or molly bolt, often misspelled moly,[1] is a formerly trademarked[2] name for a specialized screw fastener used with drywall, as a hollow-wall anchor. Larger sizes permit reasonably heavy objects, such as shelving, flatscreen-TV mounts or central-heating radiators to be attached to drywall in locations where there is no stud behind the drywall. For heavy objects, multiple molly bolts may be required.

Attaching[edit]

The fastener is an anchor, an expandable sleeve that slides into a hole drilled into the wall. A lip wider than the hole prevents it from falling behind the wall. A machine screw is then screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the drywall.[1]

Mollies come in various diameters and "grip lengths" for different drywall thicknesses and to support different loads.[1]
