Shaft collars for 5/16 inch shafts

This pack contains four shaft collars sized 5/16 by 5/8 by 5/16 inches. They suit hobbyists and maintenance teams who need to position components on small-diameter shafts. The transparent finish lets users confirm alignment at a glance. Buyers who want more storage options or different bore sizes will need a separate kit.

Easy hand installation

Each collar slides onto the shaft and secures with a single set screw, so no special tools are required. The main issue is over-tightening the screw, which can mar the shaft or strip the threads. A light touch and a hex key prevent damage and keep the collar removable.

Limits of set-screw clamping

The holding force relies on friction between the screw tip and the shaft surface. Vibration or axial loads can cause the collar to slip if the screw loosens over time. Periodic re-checking is the only way to maintain position on a rotating shaft.
