Finally, cap screws with a proper hex socket that doesn't strip out on the first use. I used these to rebuild a jig for my drill press, and each one seated perfectly with no wobble. The black oxide coating looks clean and should resist rust in a humid shop.

Used these to secure a jig on my mill table and the hex socket drive made installation a breeze with a standard Allen key. The black oxide finish gives them a clean look and seems to resist minor rust so far.
