1/4-20 x 2 Brass Button Head Socket Cap Screw helps designers combine a compact rounded head profile with material properties useful for electrical and instrumentation work. This head style is a practical choice where the fastener should remain accessible while presenting a compact rounded profile. Because brass is non-ferrous, it can be useful in selected electrical, instrument, and laboratory applications where magnetic response is undesirable.

Appropriate uses include laboratory equipment and commercial fixtures, where non-ferrous construction and a clean exposed head are often preferred over plain steel hardware. It can also fit laboratory equipment and commercial fixtures, where non-ferrous construction and a clean exposed head are often preferred over plain steel hardware. The internal hex drive supports socket-key installation in compact equipment without relying on an external wrenching surface.
