0-80 x 3/8 Alloy Steel Button Head Socket Cap Screw is selected for socket-drive fastening where head projection, appearance, and bearing area all matter. The alloy steel construction is used in machinery repair where a rounded head and socket-drive access help keep service work straightforward.

Suitable assembly locations include brackets, fixtures, and tooling assemblies where the broad head distributes contact over a wider seating area. The same head style is useful for brackets, fixtures, and tooling assemblies when the broad head distributes contact over a wider seating area. Selection is usually driven by head shape, socket access, and exposed-surface requirements rather than by the geometry of a standard socket head cap screw.

When checking fit for the 0-80 thread and 3/8 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below support counterbore planning, socket access, and replacement matching.
