Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The threading is clean and consistent across all 1200 pieces, and the Grade 8 yellow zinc finish looks properly applied. These seated perfectly in my fixture plates with a socket wrench, no stripped heads or binding.

Riley ★★★★★

The threading is clean and uniform across all 1200 pieces, and the yellow zinc finish looks consistent on every single one. I've used about half of them for equipment mounting and haven't had a single stripped head or binding issue.

Ryan I. ★★★★★

Finally got around to replacing some old hardware on my press brake with these, and the yellow zinc makes them easy to spot during teardown. The 3/8-24 thread cut cleanly into the tapped holes without any binding.
