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.

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

Worked as intended. Good machining. I also drilled and tapped some smaller set screws with no issues.

Well made, great price, quick shipping

Perfect for project

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.

Not sure about this one

Work great

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

Excellent product well-made works perfect!
