Leo P. ★★★★★

The yellow zinc finish on these L9 bolts is exactly what I needed for the assembly line—no galling when torqued down, and the fully threaded length gives me room to adjust. Packed fifty to a box, so I’ve got spares for the next job.

Henry ★★★★★

The hex head grabs my socket perfectly without slipping, and the yellow zinc finish has held up well against light moisture in my shop. These fully threaded 1-1/4" length screws were exactly what I needed for a bracket repair on my milling machine.

Julian ★★★★★

The fully threaded design made these super easy to cinch down tight on my press jig. I was glad to find Grade L9 alloy steel in a standard hex head, the yellow zinc has a nice consistent finish too.
