براغي رأس كبس 7/8-14 × 2-1/2" | رأس مسطح بمحرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مع أكسيد أسود حراري (10/عبوة)

These flat head screws fit perfectly into my jig fixture, and the hex socket drive made installation much easier than a standard slot. The USA-made quality is obvious in the precise threading.

I was skeptical about the black oxide coating holding up on these, but after torquing them down for a jig, they still look perfect. The alloy steel feels stout compared to the cheap ones I usually grab.

I needed a batch of black oxide screws for a jig I'm building, and these went in smooth with a hex driver—no cam-out at all. The 2-1/2" length was perfect for a thick steel plate, and the threads caught cleanly without any binding.
