براغي رأس سداسي ثقيلة 7/8-9 × 6 بوصة | ASTM A193 B7 سبائك فولاذ عادي | ملولبة جزئيًا (30 / عبوة)

I needed heavy-duty fasteners for a press frame, and these B7 alloy screws handled the torque without any issues. The threads were clean and uniform right out of the package.

These worked perfectly for bolting down a heavy press in my shop. The 6-inch length gave me plenty of grip, and the B7 alloy steel feels seriously tough.

I was a bit worried about getting the right size for my industrial press rebuild, but the 7/8-9 threads cut smoothly into the tapped holes and the 6" length was spot-on. The plain alloy steel finish has a nice, uniform look and the partial threading made it easy to snug them down without binding.
