I needed these for a jig I’m building, and the threads fit perfectly into the tapped holes—no binding at all. The hex socket drive made installation easy with just an Allen key.

The black oxide finish on these M20 screws cleaned up nicely without any residue, and the hex socket drive made tightening them into a jig frame much easier than with a standard bolt.

I needed some heavy-duty fasteners for a jig I'm building, and these M20-2.5 x 55mm screws threaded in smoothly without any binding. The hex socket drive gave a solid grip, and the black oxide finish looks clean and professional.
