Customer Reviews (4.6 / 5 · 5 reviews)

Ruby ★★★★★

The threads are clean and consistent across all 100 pieces, which made assembly on our equipment line go smoothly without any cross-threading issues. Yellow zinc finish looks uniform and should hold up well in the shop environment.

Ellie C. ★★★★★

Got these for a jig I was building and the threads were clean right out of the bag, no burs or binding at all. The Grade 8 yellow zinc finish looks tough enough to handle the torque without stripping.

Madison V. ★★★★★

Finally, some 3/8-24 bolts that actually fit my torque spec without stripping — the Grade 8 steel is tough as nails. The yellow zinc finish looks clean and hasn’t shown any rust after a week of outdoor use.
