Stainless Steel Square Drive Pan Head Machine Screws

Diameter - Thread Pitch: 1/4"-20

Stainless Steel Square Drive Pan Head Machine Screws are often used with nuts as well as driven into tapped holes. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts.

Machine Screws in this selection are corrosion resistant 18-8 Stainless Steel and feature a Square Drive to eliminate the stripping effect sometimes experienced with other types of drives
