براغي رأس أسطواني #1-1/4-7 × 8" | محرك سداسي | خيط جزئي | فولاذ سبائكي بأكسيد أسود حراري

I needed long, sturdy fasteners for a jig build and these eight-inch partially threaded screws held up great during heavy use. The thermal black oxide finish looks clean and seems to resist rust better than I expected.

The hex socket drive made installation a breeze with my Allen wrench, and the black oxide finish looks great on my custom tooling jig. These 8-inch screws are exactly the heavy-duty fasteners I needed for a press rebuild.

These screws held up perfectly when I used them to attach a heavy jig to my workbench. The black oxide coating has a nice, even finish and the hex socket drive made installation straightforward without stripping.
