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

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.

Delivered earlier than expected

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

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

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

Very convenient, useful, reliable

Some others complained that the ID was small. Mine was good and it fit on my 1 +/-.003 shaft nicely. Set screw worked as it should.

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

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

Excellent product well-made works perfect!
