براغي رأس مقبس 7/16-14 × 5/8" | رأس مسطح مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي أكسيد أسود حراري (100/عبوة)

I’ve bought other 5/8" screws that stripped halfway in, but these fully threaded alloy steel ones seated perfectly in my jig with the thermal black oxide coating holding up nicely. Hundred count is a solid deal for the price, and they’re clean and uniform out of the bag.

I popped these into my drill jig and the hex socket drive grabbed perfectly with no stripping, even at a tight angle. The thermal black oxide gives them a nice uniform sheen, and all 100 threads looked clean out of the bag.

The black oxide finish on these screws held up perfectly when I mounted them on a drill jig—no scratches or wear after tightening with a hex key. The threads cut clean and seated flush, which saved me time on alignment. Exactly what I needed for precision tooling work without any fuss.
