Customer Reviews (4.8 / 5 · 5 reviews)

Owen P. ★★★★★

The hex socket drive made these incredibly easy to install in tight spots on my tooling setup. They feel solid and corrosion-resistant, just what I needed for marine-grade fixtures.

Joseph X. ★★★★★

Finally found 316 stainless that doesn't rust after a week in my marine shop—these hold up perfectly under salt spray. The hex socket drive makes installation in tight jig fixtures much easier than using a wrench.

Aurora ★★★★★

These hex socket screws seated perfectly flush in my jig—the 316 stainless finish is noticeably cleaner than the 304 I've used before.
