Good Buy

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

These worked fine for me and werent that expensive.

Use to adjust cart wheels to tightness

Too big

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 went on easy. Will see if they stay in place.

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!

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