Customer Reviews (4.6 / 5 · 5 reviews)

Daniel H. ★★★★★

I needed heavy-duty bolts for a press frame, and these Grade 8 screws handled the torque without stripping. The hex heads fit my socket perfectly, and the zinc plating looks like it'll resist rust well.

Owen M. ★★★★★

The threading is clean and the zinc coating looks even across all 120 pieces, which made sorting them for my jig build a breeze. These grade 8 bolts torqued down without any stripping, and the partial threads gave me just the right grip for a tight assembly.

Daniel T. ★★★★★

Picked up a box for building a press frame, and the zinc plating on these Grade 8 bolts is flawlessly smooth—no burs or rough edges to snag gloves. Each head grabbed perfectly with a 3/4" socket, and the partial threading made cinching down heavy brackets a breeze.
