براغي ذات رأس أسطواني 1-1/2-6 × 9 بوصة | محرك سداسي مجوف برأس مسطح | سبيكة فولاذية مؤكسدة حرارياً باللون الأسود

Had to swap out some worn fasteners on a jig, and these 1 1/2-6 x 9" screws slid right into place with no binding. The black oxide finish looks like it'll hold up well against shop grime.

The hex socket drive on these screws fits my hex keys perfectly with zero wobble, and the black oxide coating looks professional on my latest jig build.

The black oxide coating on these flat head screws held up perfectly during assembly without any galling. I used them for a heavy-duty jig and the hex drive seated cleanly every time. These long 9-inch bolts are exactly what we needed for deep-thread engagement.
