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

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

Excellent product well-made works perfect!

Perfect

Filled my needs on my current project.

Easy to install

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.

Been using this for home gym barbells (10-15lb weight per side) as a more stable substitute for the elastic bands I previously used and have had no issues. The diameter was exactly as described and the collars have held with no loosening after a few dozen weightlifting sessions. Granted I keep the barbell level to the ground pretty much the majority of the time, the collars have not shifted any noticable amount after a fair amount of pressure on them over the past few weeks.

Inner bore diameter is not 1”. Calipers show it was short by 1mm.

It is a good shaft lock

I like the shaft collar for there fit thanks
