Customer Reviews (5.0 / 5 · 5 reviews)

Isabella ★★★★★

The partially threaded design gave me just enough grip for securing a jig without bottoming out. These 170mm screws feel solid in hand, and the zinc plating looks clean and uniform.

Ella ★★★★★

The hex socket drive bit down cleanly without stripping, and the 12.9 alloy steel feels properly hard when torqued against a fixture. Threads were smooth and the zinc plating held up fine during assembly.

William ★★★★★

The zinc plating looks flawless and the threads are clean enough to spin on by hand before I torqued them down. These 12.9s held up perfectly in my fixture setup, no stripping or flex even under heavy load.
