Customer Reviews (4.8 / 5 · 5 reviews)

Amelia ★★★★★

The black oxide finish on these is flawless and really resists marring during assembly. I used them to secure a heavy-duty machine guard and the six-inch length gave me plenty of thread engagement without any wobble.

Nicholas ★★★★★

I needed some long cap screws for a jig I’m building, and these 6-1/2" ones are perfect. The hex socket drove in cleanly without slipping, and the black oxide finish looks like it’ll hold up.

Eli ★★★★★

These worked perfectly for the jig I’m building, and the hex socket drive made torquing them down a breeze. The 6-1/2" length feels solid and the black oxide finish seems tough so far. For a 20-pack of this size, the price feels right.
