Customer Reviews (4.6 / 5 · 5 reviews)

Eli ★★★★★

The zinc coating on these looks clean and even, and every single bolt in the pack was free of burs. I used them to mount a heavy-duty jig in the shop, no issues with the threads binding. Solid buy for the price.

Richard X. ★★★★★

These bolts threaded perfectly into a 3/8-24 die I have on a jig, no binding or cross-threading at all. I needed a full 150 pack for a large assembly job and every single head was clean and consistent. For grade 8 strength at this length, the price is tough to beat.

Samuel ★★★★★

The hex heads on these grade 8 bolts grabbed my socket perfectly, and the yellow zinc finish is a nice bonus for resisting a bit of garage moisture. I used them to rebuild a press jig and every single one of the 150 pieces chased clean. For the price and USA quality, this was a solid find.
