Customer Reviews (4.6 / 5 · 5 reviews)

James ★★★★★

The zinc plating on these has a nice, even finish and the threads are clean all the way through. I used them to bolt a heavy motor mount to a steel frame and they seated perfectly without any binding. Solid fasteners for the price.

Abigail ★★★★★

I needed fully threaded 5/8-11 bolts for a trailer hitch project, and these heavy hex heads seated perfectly with a wrench. The threading was clean all the way down, making installation quick.

Hannah D. ★★★★★

The zinc plating on these bolts looks great and should resist rust well in my shop. They seated cleanly into the tapped holes on my press frame without any binding.
