(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

Worked for what I needed

Good Buy

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

fit perfectly on axle of fertilizer spreader

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.

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.

If you are An idiot like me you should probably read the entire description because it’s not an internal bore of 5/8” however this is an solid item and is Sturdy. not five stars because I’m an idiot and I accept it and also because the product description

Too big

Ive probably bought over 100 of these collars for my mini bike, go kart and trike builds. Add a small amount of lock tight and they never move.
