1-1/8-7 × 2-1/4" براغي ذات رأس أسطواني | محرك سداسي | ملولب بالكامل | فولاد سبائكي أسود حراري مؤكسد (5 / عبوة)

The black oxide finish on these has held up perfectly in my shop, no rust even after a week of oily hands handling them. Threads were clean and the hex socket seated the wrench snugly right out of the package for my tooling setup.

Needed these for a jig I was building, and the hex socket drive let me get them tight in a cramped spot without stripping. The fully threaded body gave a solid grip, and the black oxide finish handled a little oil from my hands without smudging.

Installed these on my milling machine's hold-down clamps and the black oxide finish made it easy to see the full thread engagement. They tightened up beautifully with the hex key.
