براغي ذات رأس مقبس 7/8-9 X 6-1/2" | محرك سداسي | صناعة أمريكية | سبيكة فولاذ أكسيد أسود حراري (20 / عبوة)

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.

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.

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.
