(4-Pack) Zinc Plated Carbon Steel 5/8” Bore Shaft Collars Sets - Screw Style Bore Shaft Collars with 5/8” Bore Size, 1-1/8 Outer Diameter, and 1/2 Width - Suitable for Automotive and Industrial Use

Was just what I expected nothing more & nothing less.

Very well machined, inner diameter is 5/8 , comes with lock screw.

These worked fine for me and werent that expensive.

Seems good quality

Seller did everything right as far as I am concerned. I couldnt use them because I got the axle size wrong thus I could not put them on. But they would have been a great value and a simple fix to the issue I would of had. Great product high quality!

The ones I got were smaller than 5/8, by 1/32-1/16. Luckily I had a 5/8 drill bit and a drill press with a vise. I was able to bore them out so I could use them, but if youre not that lucky, beware, these are smaller than 5/8. I used a micrometer on the axle shaft i was using, and it came out exactly 5/8 and these would barely get on the ends. It took me 20 minutes to try and get the first one back off. The 5/8 drill bit shaved off quite a bit of metal to get them to work.

Too big

Product is as expected. 2nd order was packaged as to contain small set screw if it became dislodged. Bravo!

I saw some reviews that said these run small, but I found them perfectly sized. They were so accurately sized that I had to lightly sand some burrs off of the shaft to get them on. Locked down tightly once in place. Very pleased with these.

Worked for what I needed
