Customer Reviews (4.8 / 5 · 5 reviews)

Elizabeth P. ★★★★★

Used these to repair a press at the shop and the threads held up perfectly under heavy torque. The full threading on these B7s made installation faster than I expected.

Edward ★★★★★

These bolts threaded cleanly through pre-tapped holes without any binding, which made assembly much smoother than I expected. The plain finish is exactly what I needed for indoor equipment where rust isn't a concern.

Steven ★★★★★

The hex heads on these B7 bolts grabbed my socket wrench perfectly without any slipping, and the full threading made cinching down a heavy flange a lot easier than I expected from a pack this size.
