Customer Reviews (4.4 / 5 · 5 reviews)

Abigail X. ★★★★★

The yellow zinc finish looks sharp and hasn't chipped even after tightening them down hard with an impact wrench on our conveyor frame. Threads caught clean right out of the bag, and the partial threading made alignment on the shaft a lot less fiddly than I expected for a 12-inch bolt.

Mia ★★★★★

Putting these into a large press jig was straightforward—the partially threaded shank gave just the right grip length before the threads engaged. Priced fairly for a set of eight USA-made Grade L9 bolts, and the yellow zinc finish looks clean and consistent.

Victoria C. ★★★★★

The hex head on these bolts grabbed perfectly with my impact wrench, no slippage at all. The zinc coating has a nice, even finish that should hold up well in my shop press build.
