Madison ★★★★★

I needed some heavy-duty fasteners for a custom jig I was building, and these M16-2 x 40mm socket cap screws were perfect. The thermal black oxide finish seems really durable and the hex drive gripped the tool cleanly without any slipping during installation.

George B. ★★★★★

The hex socket drive made installing these into my jig setup surprisingly easy—no stripped heads. They feel solid and the 40mm length fit perfectly for my precision assembly. Exactly what I needed for heavy-duty tooling work.

Victoria ★★★★★

The black oxide finish on these M16-2 x 40mm screws looks really clean and seems durable for tooling fixtures. I used them to secure a heavy-duty press jig, and the hex socket drive held up perfectly without stripping. Exactly what I needed for precision assemblies.
