Customer Reviews (4.8 / 5 · 5 reviews)

Evelyn ★★★★★

Threads cut clean and the B7 alloy has that proper industrial heft you want for machinery work. The partial threading on the 4" length gives you solid grip without fighting the full shank. Grabbed a second pack for the next job.

Miles X. ★★★★★

Installed these on a heavy pump base and the partial threading made alignment much easier than fully threaded bolts. The B7 alloy steel feels plenty sturdy for industrial loads, and the hex head gave my wrench a solid grip without stripping.

Sophia ★★★★★

Threaded about an inch and a half past the head, so they grabbed cleanly in my flange mount without needing extra washers. These B7s torqued up nicely and feel solid for the heavy equipment assembly I'm doing.
