Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas C. ★★★★★

I needed a few heavy-duty bolts for a repair on an old press, and these grade 5 screws handled the torque without any stripping. The partially threaded design gave plenty of grip through the assembly, and the yellow zinc coating looks solid enough to resist rust for a while.

Hannah ★★★★★

Used these to bolt down a heavy press at the shop—the 5-inch length gave just enough thread engagement in the frame. The Grade 5 rating handled the torque without stripping, and the zinc kept them from rusting after a coolant spill.

Avery ★★★★★

The zinc coating on these feels tough and consistent, and the partial threads grabbed cleanly in my equipment frame without any wobble. For a 25-pack at this grade, the hex heads are cut sharp enough that my socket didn’t slip once.
