machine screw

It was a small inconvenience, but they were easily replaced with a few machine screws and nuts.

Provide a machine screw, S, for the hole C and drill a small tapered hole in the end of the screw.

When a machine screw is turned around just once, it moves forward a certain distance, as a glance at Fig. 36 will show.

A bolt or machine screw was threaded 151 through the nut, so that its inner end pressed against the sighting rod.

It was a real big screw, as they go, a 4-40 flat head machine screw with a length of about three-quarters of an inch.
