Flat Head Socket Cap Screws

Flat head socket cap screws for flush-mount applications where moving parts pass over the fastened area; partial threading gives better alignment.

Special socket products are machined from bar where the specification allows, with the socket broached and the threads rolled, or cut where the specification or order allows, then heat treated and plated as the specification requires. Shoulder, low-head, flat-head and set-screw patterns follow ASME B18.3 unless the drawing says otherwise.
