#10-32 × 7/16" براغي رأس مقبس | رأس منخفض سداسي المقبس | فولاذ سبائكي مؤكسد أسود حراري (200 / عبوة)

Paid a bit more for the alloy steel and black oxide finish versus plain stainless, and it shows—no galling when I torqued them into my jig frame. The 7/16" length was dead-on for the 3/8" plate plus washer, and all 200 came out of the bag with clean threads.

The hex socket drive seated perfectly on my driver without any wobble, and the black oxide finish has a nice even coating that hasn't flaked off after a week of assembly work. These little low-head screws are exactly the right height for my jig setup.

I needed low-profile fasteners for a tight jig assembly, and these hex socket screws fit perfectly without sticking out. The 7/16" length was exactly what my fixture required, and all 200 pieces had clean threads that started easily.
