Climax Metal C-100 Shaft Collar, Zinc Plated Steel, Set Screw Style, One Piece, 1 Bore, 1-1/2 OD, 5/8 Wide, With 5/16-18 Set Screw

exactly as advertised, excellent quality.

Put on my go kart axle 1 inch to align sprocket. worked great

works

Overall is best value for what you pay. It does the job holding the rear axle in place on my vintage quarter midget. I wouldnt install it for more for racing or something that needs more durability. But it gets the job done. Its also slightly bigger than the measurement than for the size I ordered.

Picture shows a set screw and the ones I got did not have a set screw. I had to return and order a different part.

These are great BUT, they are 5/16 24 and NOT 5/16 18.

Good price & quality

Listed as 5/16 - 18 thread pitch but was actually 5/16 - 24. Rather than that they are the correct diameter and well made

I bought this to use as a replacement for a squirrel baffle. It is not suitable for that purpose. I do not know what its purpose is. Apparently, its good at what it is meant to be used for, but not for being a squirrel baffle. Baffled.

This is a well-made product at a great price and fits my motor shaft perfectly.
