Review: Quality Product - I used this to make a solid axle with wheels on a generator. A number of reviews have stated this shaft does not properly fit 1/2" ID bearings, collars, etc. I ordered this shaft, collars ( 1/2" ID) and push nuts (1/2" ID) and two 12" tall wheels w/ 1/2" ID bearings. This shaft fit them all just perfectly. I also received an empty box on the first order, the box had a small hole in it and nothing inside. desertcart was nice enough to credit me back and I reordered but this delayed my project for another week. desertcart shipping did not make any adjustments to the shipping container or packing, but somehow the second shipment made it just fine. It really makes me wonder just how much force these boxes take en route to cause the shaft inside to propel with enough force to bust out of the box. Whether or not this is an desertcart or post office issue, this could easily be avoided by just wrapping the ends of the shaft with a wad of scrap paper and a rubber band or the manufacturer could dip the ends in a hot plastic that cools quickly and provides a removable end cap/tip. Either would probably solve this shipping problem. Regardless, this is a quality product, well made, very hard, zinc coated, straight, and tough.
Review: Arrived fine. - Worked perfect for axles under my potable generator.
