براغي كاب مقبس 1/2-13 × 2-3/4 بوصة | محرك مقبس سداسي | صناعة أمريكية | فولاذ سبائكي أكسيد أسود حراري (25/عبوة)

Installed a batch of these into a new jig I was building, and the hex socket drive made torquing them down effortless. The alloy steel feels really solid, and the black oxide coating gives them a clean, professional look. Exactly what I needed for a heavy-duty fixture.

The black oxide finish on these screws has a nice, even sheen that looks professional in my tooling setup. Threads cut cleanly into my fixture plates without any binding, and the hex socket fit my Allen wrench perfectly the first time.

I needed these for a jig I was building, and the hex socket drive made installation much easier than using a hex head bolt. The 25-pack gives good value for the price, too.
