Customer Reviews (4.8 / 5 · 5 reviews)

Joseph ★★★★★

Pulled these out of the box and the black oxide finish looks really clean, they thread smoothly into an aluminum jig I’m building. The 12.9 grade steel feels plenty strong for the small precision assembly work I use them for.

Hazel T. ★★★★★

Installed these in a jig I'm building and the hex socket drive made tightening them in tight spots so much easier. The 45mm length was perfect for the application I needed, and all 200 in the pack have consistent threads.

Ruby ★★★★★

The black oxide finish holds up well in my jig setup, and the hex drive makes installation quick. These are a perfect fit for precision assemblies where a standard cap head wouldn't work.
