Brian Q. ★★★★★

The yellow zinc coating on these L9 alloy screws looks tough and even, and the full threading made aligning the equipment frame a breeze. They seated cleanly with a socket wrench and held tight without any stripping.

Sophia ★★★★★

These threaded all the way down, which made a big difference when I needed to fasten a bracket to a steel beam. The L9 alloy feels plenty sturdy for heavy equipment.

George ★★★★★

The yellow zinc coating is holding up nicely under some pretty greasy conditions in my shop, and the hex head grabbed my socket without any stripping. These L9 alloy screws feel solid, and for a dozen in a package, they’re a fair deal for what they’re made to do.
