Samuel ★★★★★

The partial threading on these M5 screws makes them ideal for jig work where you need a smooth shank. Class 12.9 alloy steel feels solid, and the zinc plating gives a clean, rust-resistant finish. Pack of 300 should last me through several projects.

Brian ★★★★★

I needed a batch of high-strength fasteners for a jig I’m building, and the partially threaded design on these makes assembly much easier. The zinc plating looks clean and should resist rust well in my shop.

Mia ★★★★★

These M5 screws have been perfect for securing brackets on a small jig I built; the 12.9 alloy steel feels incredibly tough. The partially threaded shaft gave just the right grip depth without bottoming out. Exactly what I needed for precision work.
