Customer Reviews (4.4 / 5 · 5 reviews)

Robert ★★★★★

The yellow zinc finish on these is holding up great so far, even after I left a few sitting in a wet toolbox overnight. Threads ran clean into the bracket without any binding, and the hex heads took a socket wrench with zero fuss.

Matthew ★★★★★

These threads cut clean and started without any binding thanks to the consistent yellow zinc finish. I used them to mount a heavy-duty vise to a steel workbench and the hex head gave my socket wrench a solid grip.

Alexander Z. ★★★★★

I needed some heavy-duty bolts for a press rebuild, and these fit perfectly with zero wobble. The threads started cleanly by hand, and the yellow zinc finish looks like it’ll hold up well.
