Customer Reviews (4.8 / 5 · 5 reviews)

Eva Y. ★★★★★

Used these for a jig I was building and the hex heads let me get a socket in a tight spot. The yellow zinc coating seems consistent across all 500 pieces with no bare spots.

Lucy ★★★★★

I needed a bulk supply for a small fabrication project, and the yellow zinc coating on these M6-1 x 20mm screws feels nicely corrosion-resistant right out of the box. The threads are clean and consistent, which saved me time during assembly.

Andrew M. ★★★★★

The yellow zinc coating is evenly applied with no bare spots, and the threads are sharp enough that they started cleanly in steel without any galling. I used about a hundred of these on a conveyor frame and not one stripped or rounded off. Solid purchase for the price.
