Customer Reviews (4.4 / 5 · 5 reviews)

Eva N. ★★★★★

The hex heads are a perfect fit for my socket wrench, and the 18/8 stainless steel feels solid and corrosion-resistant. I used them to secure some heavy machinery panels, and every single screw threaded smoothly without any binding. Great value for a bulk pack of 300.

Andrew I. ★★★★★

These are exactly the length I needed for a repair, and the 18/8 stainless feels solid — the threading is clean, no burrs. I've used all 300 across a few projects and haven't stripped a single one.

Richard ★★★★☆

The hex head made tightening them with a socket wrench a breeze, and the 18/8 stainless steel seems solid enough for outdoor use. Only slight downside is the 55mm length felt a bit long for my particular setup, but that's on me for not measuring twice.
