Customer Reviews (4.8 / 5 · 5 reviews)

Ellie O. ★★★★★

The hex socket drive sits flush and grips the allen key perfectly—no stripped heads even after torquing them down in my jig. Full threading on all 400 made alignment effortless, and the 18/8 steel shows zero corrosion after a week in a damp shop.

Steven ★★★★★

I needed a bulk pack of M4 screws for jig assembly and these fully threaded ones are perfect—the 18/8 stainless feels sturdy and the button head sits flush.

Charlotte I. ★★★★★

The hex drive on these M4 screws bit cleanly into my allen key without any slipping, which was a relief after struggling with cheaper ones. A full 400-count bag gives me plenty for my jig builds, and the 18/8 stainless feels solid.
