7/16-20 × 1-3/4" مسامير ضبط نقطة مسطحة رأس سداسي داخلي | فولاذ سبائكي (100/عبوة)

Needed these for a jig adjustment and the hex socket drive made tightening them in a cramped spot much easier. The alloy steel feels solid, no stripping so far.

The flat point tip seated perfectly into the dimple on my shaft without walking off-center, and the alloy steel feels dense enough to trust under heavy torque. I've used cheaper sets that stripped out, but these grabbed the hex wrench cleanly every time. Solid value for a hundred of them.

The hex socket drive made cinching these down in a cramped gearbox housing a breeze—no rounding off the drive like I've dealt with before. Flat points seated firmly on the shaft without walking, and all 100 came out of the box clean and burr-free.
