(4-Pack) Zinc Plated Carbon Steel 5/8” Bore Shaft Collars Sets - Screw Style Bore Shaft Collars with 5/8” Bore Size, 1-1/8 Outer Diameter, and 1/2 Width - Suitable for Automotive and Industrial Use

Worked for what I needed

Ive probably bought over 100 of these collars for my mini bike, go kart and trike builds. Add a small amount of lock tight and they never move.

It was a struggle to fit this on a 5/8 shaft.
