Good fit
These fit great, and had previously been hard to find. Amazon found them for me. A little more expensive that I remembered, but a much needed item. Worth the cost because I couldn't find them anywhere else and I couldn't finish my project without them.

Too exspensive
I never ever thought that these would be the cheapest I could find! They work as expected, bot the price is crazy high for what they are!

Well Made and Work
Used to hold new wheels on axle of pressure washer. Takes some effort to get them on, but that is likely why they stay on. Seems to be well made.

Larger sizes are a bear to install.
Product arrived quickly and was exactly what I wanted. But beware that at this 3/4" diameter size they are very difficult to install and I had to beat them on my axle with a very larger 4 lb. hammer. Both that I tried to install became so deformed that I abandoned my plan and elected to drill a new hole and use a cotter pin. These things might work okay for diameters less than 1/2" but anything larger will probably yield the same results as I experienced unless you can access the axle and use a hydraulic press. Good luck.

Rock Solid
Perfect fit for the axle on my deer chart. No more cottar pins lost and wheel falling off. A drop of lock tight and this thing is rock solid.

These were an excellent way to secure wheels and washers onto a shaft or rod axle. They fit really tight, and will not come off or loosen as long as they are not abused or hammered on to hard, which will compromise the original conformation.
