National Hardware N179-812 4005BC Smooth Rod in Zinc plated,5/8" x 36"

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. Amazon was nice enough to credit me back and I reordered but this delayed my project for another week. Amazon 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 Amazon 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.

Worked perfect for axles under my potable generator.

Worked well for an axle.

I had to cut nearly an inch off of each end to remove the deformed portions. It is exactly .75" diameter however, so it worked for my application.

The machining was smooth, straight and of good quality. The quality metal, combined with good manufacturing, provides for a great fitting rid. I used a couple of pillow mount bearing brackets to create a very solid rolling axle for my smoker. This is a good value part.

Great product

I was using this as an axle and I bought single set screw collar that would not fit. I don’t know whether it was the axle that was just a little bit too big or the collar that were too small either way if you’re gonna use it as an actual type use the split color it works so much better.

This is just cheap plated rod like what you would find at a home improvement store. It wasn't as straight as I had hoped and the fact that I used it with cheap bearings didn't help. The price seems a bit high for what it is, but I didn't compare it to the price at the home improvement store. I should have just bought mild steel rod at my industrial metal supplier, but this saved me a trip. Last time I needed a similar material, I purchased precision ground rod. Well, this doesn't come close to that and it is almost the opposite. What I was hoping for was something in between cheap rod and precision ground rod........maybe there isn't such a thing. It looks like it will get the job done, since this will be for a shaft that only rotates 90 degrees, but I wouldn't recommend it for a spinning shaft, especially at higher rpm. It didn't appear that it was bent, but just that it was not made to have a tight tolerance for straightness.
