Customer Reviews (4.8 / 5 · 5 reviews)

Andrew ★★★★★

Used these to secure a motor mount on a lathe and the threads engaged cleanly with no galling. The hex head gave my socket a solid grip for torquing down properly.

Violet ★★★★★

Needed a reliable set for a small winch mount I was building, and these grade 5 hex heads seated perfectly without stripping. The yellow zinc finish is a nice touch for basic corrosion resistance, and the 200-count pack should last me a while.

Elizabeth ★★★★★

Picked up these for a quick jig repair on my drill press—the yellow zinc coating makes them easy to spot in my bin, and the 200 count was more than enough. They threaded in smoothly with a socket and held tight.
