Customer Reviews (4.8 / 5 · 5 reviews)

Leo ★★★★★

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.

Michael G. ★★★★★

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.

Mia O. ★★★★★

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.
