Customer Reviews (4.6 / 5 · 5 reviews)

Ruby H. ★★★★★

Installed these on a custom machinery guard and the silicon bronze held up perfectly under vibration, no corrosion worries. The hex socket drive made them easy to set with just a standard Allen key.

Ruby P. ★★★★★

The hex socket drive made it easy to tighten these into my metalworking jig without stripping. The silicon bronze feels noticeably robust compared to regular steel screws I've used before.

Madison ★★★★★

Perfect fit for my jig assembly, and the hex socket drive made installation much easier than a standard slot. The silicon bronze finish gives them a nice look compared to plain steel screws I’ve used before.
