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

Easy to install

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

While it was exactly what I was looking for and exactly 1 inch, the pipe 1 inch pipe I wanted to slide this collar onto had a light coat of paint and because of the paint the collar didnt easily slide onto the pipe. I had to strip some of the paint off and with a little bit of oil the collar slid right into place.

This collars looks good and and shine, the way how I spect.

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 pieces. Very happy.

Perfect

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

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.

Picture shows a set screw and the ones I got did not have a set screw. I had to return and order a different part.
