Tamper-Pruf Screws 91190 machine screw is a type of fastener with a threaded shaft designed to be used with a nut or in a tapped hole.

It has a spherical profile and provides a wider bearing surface with higher tensile strength than socket cap screws.

A. A machine screw consists of three primary parts: the head, the shaft and the thread. The head may be flat, oval, round or another shape and provides a surface for tightening the screw. The shaft is the straight portion of the screw between the head and the thread. The thread is the helical ridge that wraps around the shaft, allowing the screw to grip the material it's being fastened into.
