Customer Reviews (4.6 / 5 · 5 reviews)

Carter N. ★★★★★

The yellow zinc finish has a nice, consistent shine that makes them look almost too good for the shop floor. The hex heads fit a wrench perfectly with zero stripping, and the partial threads grabbed cleanly when I was bolting a heavy bracket into place.

Alexander ★★★★★

The partial threading on these bolts made aligning them in tight engine brackets so much easier than fully threaded ones. They torqued down smoothly without any binding, and the hex heads grabbed my socket perfectly.

Madison ★★★★★

I needed a strong fastener for a heavy jig I was building, and these L9 alloy steel screws are definitely tougher than the standard ones I’ve used before. The hex head fit my socket perfectly, and the threaded portion was just right for the application.
