Customer Reviews (4.8 / 5 · 5 reviews)

William M. ★★★★★

The threads are clean and fully cut the whole way down, so they started smoothly without any cross-threading on my equipment frame. I've used a lot of hex bolts over the years, and the zinc finish on these feels more durable than what I usually get, held up fine when I torqued them to spec.

Penelope ★★★★★

Zinc plating is smooth and even across all 100 bolts—no flaking or thin spots like I've seen with cheaper packs. These heavy hex heads gave my equipment assembly a solid, snug fit without any stripping issues.

Stella D. ★★★★★

Threads were clean and gauge-perfect, so the nuts spun on without any binding — that's rare for bulk hardware. The full threading on these 3/4-10s made them ideal for the equipment base I was rebuilding, and the zinc finish is holding up fine so far.
