Customer Reviews (4.8 / 5 · 5 reviews)

Jason V. ★★★★★

The yellow zinc finish looks uniform across all 3200 pieces, and the fully threaded shaft makes them easy to hand-start before torquing. They’ve held up fine in our jig builds without any stripped hex heads so far.

Steven ★★★★★

Installing these on a conveyor line was straightforward since the hex heads grab securely with a socket. The yellow zinc coating looks consistent across all 3200 pieces, which is nice for a uniform finish. Exactly what I needed for heavy-duty equipment assembly.

Joseph J. ★★★★★

The yellow zinc coating on these M6 screws looks consistently applied, and the hex heads fit my socket perfectly without any stripping. A solid choice for rebuilding a jig at the shop.
