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

I purchased one 1 inch ID (inside diameter) as a reference sample for future Purchases. Its lite weight. Brushed aluminum clean finish. set screw is iodized black finish. Smooth operation. Included are two Allen wrench/Allen key. I recommend this product.

This items rusts very quickly. Other than that, its a nice piece that works well.

I liked the body of the of this shaft collar, and the only reason for the 3 stars is the threads as stated is wrong. I ordered thumb screws for these and it turned out that the set screw is 5/16-24 and not 5/16-18 as stated. It turns out that 5/16- 18 would have been better as there are more options in the size thread.

Good fit

Shaft collar worked finr

Perfect

Low price for a quality part. As advertised. I am buying more.

These things are the best standard barbell collars that I have ever come across. They keep the weight extremely tight to the bar. The only issue is that there is a great deal of variation in the the diameter of standard barbells…so check first before ordering.

exactly as advertised, excellent quality.

Work great
