Customer Reviews (4.8 / 5 · 5 reviews)

Madison Z. ★★★★★

The threading was perfect for tightening down some jig fixtures on my mill table. These 8-1/2" Grade 8 bolts held up without any stripping, and the yellow zinc coating looks fresh.

Christopher N. ★★★★★

Needed these for a heavy-duty press repair, and the Grade 8 rating gave me confidence they'd handle the torque. The yellow zinc coating is clean and uniform, no burs on the threads.

Hannah E. ★★★★★

The threading on these bolts engaged smoothly without any binding, which made mounting my press brake a lot quicker than I expected. The yellow zinc finish looks durable, and the hex heads held up well under my impact wrench at 450 ft-lbs.
