3/4" Bore Solid Steel Style Zinc Plated Set Screw Shaft Collars for Wheelbarrow, Rifle, Cart Cottar Pins

These are high quality, with a smooth finish, and function as they should. I used two on my grill to hold the wheels on instead of the cheap push caps. These are a great value, and with proper installation hold very well.

I used these collars for retaining a 1/2" cart axle shaft. So much easier than drilling and using cotter pins and far more adjustable. Nice finish on the material, but I did use copper anti-seize on the set screws to prevent corrosion seizure problems.

These work great and fit perfect.

Bought these to make a replacement roller with an offset hole for tensioning a rip fence on a table saw. Knew I'd have to grind the 1.5" O.D. to a new shape. Cut and ground to the new profile, the steel machined well. The I.D. was proper already and the thickness (9/16) was also correct. The 5/16-18 set screw hole will be where the handle attaches. good, smooth zinc electroplate, no burrs.Only needed one but I'll keep a spare and give the other two away, the price for 4 of this size was too good to pass up ($9). Could have bought just one from elsewhere but would have been nearly as much and then no spares in case I screwed up. I'd trust this supplier for other similar things.

Got this as a cheap alternative to collars, works on barbells .99 mm and less. My newer barbells are 1.01 mm but older ones are .99. I also replaced the 5/16 thread screw with ones I found here on Amazon.Gonna try 1 1/8 inch collars next

these collars will just great thanks. William

The dimensions on this part were spot on, and it fit my application perfectly. This was better and cheaper than other sources.

I am using these collars to hold my wheel bearings on the shaft in alignment, so that bearings do not come out off wheels. This is a small metal cart pulled by lawn mower too move items around my property. Just installed will see if they will hold-up.
