Customer Reviews (4.6 / 5 · 5 reviews)

Henry C. ★★★★★

The hex drive on these was a perfect fit for my socket wrench, making assembly of a workbench bracket much faster than with Phillips heads. The yellow zinc coating looks consistent across all 400 pieces, and they thread cleanly without any binding.

Timothy ★★★★★

Used these for a jig I was building and the yellow zinc finish held up nicely against some scraping. Grabbed a couple with a socket wrench and the hex heads seated perfectly, no stripping. For 400 pieces at this price, I'm set for years of shop projects.

Eli ★★★★★

Threads ran smooth all the way down into the steel bracket with no galling, and the yellow zinc coating hasn't chipped even after tightening down with an impact driver. Perfect for the small machinery repairs I had on the go.
