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

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

Set screw size is not correct. Please stop selling these with 5/16-18 in the description.

I have been using these in place of spring clips for a 1” barbell. I find them much easier to use with an extra Allen wrench on hand than the spring clips, and they remain very secure even at weights over 100 lbs.

Great collars, using them on old/ smooth standard 1 inch dumbbell handles.

WTF Amazon? To be fair, this is a review of Amazon. This item, sure it was less than $2, but still, it should have been new. Plastic bag was torn open the item was dirty and used, that set screw needed to be replaced because the head was stripped out. Not worth my time replacing. I did receive another a few days earlier and it was fine.

Perfect

This worked perfectly for me. I purchased a MERAX pulldown machine with standard (1 inch) weight bar. It came with an adapter to Olympic plates, but it meant I needed 2 spring clips: one for the 1”-2” adapter and one for the 2” plates. I used this as a semi-permanent collar. It holds the adapter and allows the Olympic weight to slide over. Perfect.

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.

duper goog

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