براغي ذات رأس أسطواني 1-1/2-6 × 8" | محرك سداسي برأس مسطح | فولاذ سبائكي مع أكسيد أسود حراري

These are for a fixture I'm building, and the hex socket drive seated perfectly without stripping, which I appreciate. The 8-inch length gives me plenty of grip for the deeper holes, and the black oxide finish looks clean and consistent across all of them.

The black oxide finish feels properly done—no rough edges or uneven spots, and the alloy steel is reassuringly rigid when I’m torquing them into a jig. These 8-inchers thread cleanly into tapped holes without binding, which is more than I can say for cheaper sets I’ve used.

The hex socket drive made it easy to tighten these into my jig without stripping the head. The black oxide finish looks clean and seems durable enough for repeated use in the shop.
