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

Very well made. Feels nice. Solid piece. Perfect inner diameter almost to a fault. It was so perfectly cut to 1 ID that it was sort of tight. Wasnt too much trouble though just had to slide hammer it in. Very secure hold once the hex is tightened down. Highly Recommend!

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

works

Used to try to make my flag less able to get wrapped up.

exactly as advertised, excellent quality.

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

Seems like a good quality of steel

Been using this for home gym barbells (10-15lb weight per side) as a more stable substitute for the elastic bands I previously used and have had no issues. The diameter was exactly as described and the collars have held with no loosening after a few dozen weightlifting sessions. Granted I keep the barbell level to the ground pretty much the majority of the time, the collars have not shifted any noticable amount after a fair amount of pressure on them over the past few weeks.

I keep thee around great for many uses around the shop.
