A machine screw is screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the hole or behind it (in hollow contexts such as drywall over stud cavities, or hollow doors). [1] Mollies come in various diameters and grip lengths (shank lengths) for different drywall thicknesses and to support different ...
The screw is fastened by hitting the head with a hammer and is not intended for removal. [2] drywall screw: Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, but it is a versatile construction fastener with many uses.

Chemical locking methods create friction after the breakaway torque. The prevail torque is usually higher than zero since the cured polymer still creates friction when rotating the nut. [citation needed] Safety wire (lockwire) Holes are drilled in nuts and bolt heads, and wire is threaded through the holes to prevent back-rotation.
The tapped hole (or nut) into which the screw fits, has an internal diameter which is the size of the screw minus the pitch of the thread. Thus, an M6 screw, which has a pitch of 1 mm, is made by threading a 6 mm shank, and the nut or threaded hole is made by tapping threads into a hole of 5 mm diameter (6 mm − 1 mm).
By drilling a small pilot hole into the material, into which a screw is then driven, less wedging takes place, thereby reducing the likelihood of the material being split. [2] When a screw is driven without a pilot hole, or with too small a pilot hole, the core of the screw may bind and lead to the screw being broken.
