براغي رأس كبس مقبس 1-1/8-12 × 6 بوصة | محرك مقبس سداسي | خيط جزئي | فولاد سبائكي أكسيد أسود حراري

The hex drive on these 1-1/8-12 socket cap screws fits my socket wrench perfectly, no wobble at all. They threaded smoothly into my jig setup and the 6-inch length was just right for the assembly.

The black oxide finish is holding up beautifully in my jig setup, and the hex socket drive grips like it should on the first try. These 6-inch alloy steel screws feel rock solid for heavy machinery work, no stripping or wobble so far.

Finally got around to replacing the old bolts on my press fixture, and these cap screws threaded in smoothly with the hex drive. The black oxide finish feels nice and durable, no galling during installation.
