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

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

Installs easily

Used for a shop made spinning drum to drag the lawn and make it level.

I like the shaft collar for there fit thanks

It is a good shaft lock

1 inch steel collars with hex/ allen wrench screw. Fantastic collars. I originally bought four for two of my weight dumbbells. I just bought eight more for some of my other 1 inch weight dumbbells. Great quality. Tightened the screw with an allen wrench I had and it feels very tight. Perfect fit. Dont make the same mistake I did and buy those cheap plastic 1 inch collars. Instead by the solid steel 1 inch collars. The picture has an example of the cheap plastic ones that you dont want to buy. In the picture I also left the twist collar on too only because I had room but I would feel very comfortable just to put this collar on if I ran out of room on the bar.

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!

Item arrived on time and worked great.

exactly as advertised, excellent quality.

Good item for the price
