- UM: EA
The SSH3/8X11/4 is a socket shoulder bolt with a 3/8 precision shoulder, 1-1/4 shoulder length, and 5/16 threaded end, black oxide finish. The ground shoulder provides tight dimensional control for locating, bearing retention, pivot, and cam follower applications. Alloy shoulder bolts are heat treated for strength — standard for tooling, automation, and precision machinery. Drive: 1/4" hex key. Meets ASME B18.3.

Shoulder bolt sizing: The shoulder diameter and length define the precision fit feature. The threaded end (smaller diameter) engages a tapped hole to secure the bolt. For bearing retention, match the shoulder diameter to the bearing bore. For pivot applications, the shoulder clearance hole diameter should match the shoulder OD closely.
