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

Good fit

Well machined with a good finish and appropriate fit on the shaft.

Overall is best value for what you pay. It does the job holding the rear axle in place on my vintage quarter midget. I wouldnt install it for more for racing or something that needs more durability. But it gets the job done. Its also slightly bigger than the measurement than for the size I ordered.

It is a good shaft lock

Inside diameter was too small to fit 1 steel tubing.

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

This is a well-made product at a great price and fits my motor shaft perfectly.

Set screw is NOT 5/16-18, its 5/16-24... at least the one they sent me. Probably doesnt matter to many, but I planned to replace the set screw with a threaded knob, so my project is now delayed while I either find a replacement or tap a new hole in this one.

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

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.
