براغي رأس كبس 5/8-11 × 3 بوصة | محرك سداسي | صناعة أمريكية | فولاد سبائكي أسود حراري (25 / عبوة)

The hex drive seated perfectly on my torque wrench, and the black oxide finish has held up well against rust so far. These feel much sturdier than the imported ones I used to buy for my tooling fixtures.

Installing these on my jig setup and the hex socket drive gripped perfectly without any stripping. The alloy steel feels solid, plus the black oxide coating adds a nice layer of protection against shop grime.

The black oxide finish looks sharp and held up fine during assembly of a heavy jig I built last weekend. Threads cut clean with a tap wrench, and the hex socket drive seated snug without stripping. Solid batch for the price.
