Zoe R. ★★★★★

The partially threaded design on these M30s really helped when I needed a clean grip section before the threads engaged, and the 18/8 stainless feels solid against my wrench.

Leo C. ★★★★★

The hex head on these M30 screws gave my wrench a solid grip when I was tightening them onto a heavy-duty equipment frame. The partially threaded design made alignment easier than I expected for such large fasteners.

Elizabeth ★★★★★

Used these to secure a motor mount on a workbench and the 18/8 stainless steel feels solid and rust-resistant. The hex head drove in cleanly with a socket, and the 150mm length gave plenty of grip.
