#6-20 x 1/4 Self-Tapping Screws, Type AB, Phillips Pan Head, Fully Threaded, 18-8 Stainless Steel

A thread-forming screw with spaced threads and a gimlet point.

Self-tapping screws are best used in applications where an object is going to be disassembled and reassembled on a regular basis. One example of this is a piece of machinery that requires consistent maintenance. Contrary to self-drilling screws, a self-tapping screw requires a pilot hole to be drilled first.
