3/8-16 x 2 Brass Button Head Socket Cap Screw gives buyers a defined brass button-head fastener for equipment where appearance, conductivity, and serviceable socket access matter. 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 precision instruments and panel hardware, where the broad bearing surface can help seat the head cleanly on covers or brackets. It can also fit precision instruments and panel hardware, where the broad bearing surface can help seat the head cleanly on covers or brackets. The internal hex drive supports socket-key installation in compact equipment without relying on an external wrenching surface.
