Customer Reviews (4.6 / 5 · 5 reviews)

Edward ★★★★★

Needed a strong bolt for a jig rebuild, and the 12.9 grade on these is exactly what I was after. The partially threaded shank made alignment a lot easier than I expected.

Chloe M. ★★★★★

The black oxide coating on these M20 screws looks great, and the flat head sits perfectly flush in my jig plate. They threaded cleanly into 12.9 tapped holes without any binding.

Amelia K. ★★★★★

I needed these for a jig setup on a milling machine, and the black oxide finish is holding up nicely without any rust after a few days in a damp shop. The hex socket drive engaged cleanly without stripping.
