Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin ★★★★★

Used them to rebuild a piece of heavy equipment on the shop floor and they held up without any sign of stripping, even under a high-torque impact gun. The threading is clean and consistent across all 40 bolts.

John H. ★★★★★

These bolts torqued down perfectly on my press jig without any of the galling I've seen with softer steel. The hex head held up beautifully under a lot of force.

Matthew ★★★★★

The partially threaded shank made it much easier to start these in a tight motor mount, and the hex head held up perfectly under a torque wrench.
