Christopher ★★★★★

Used these in a conveyor frame repair and the 9-inch length gave me plenty of thread engagement in the tapped hole. The threads cut cleanly and the hex drove smoothly without any galling. Exactly what my industrial setup needed.

William D. ★★★★★

I needed heavy-duty bolts for a press rebuild, and these B7 alloy screws handled the torque specs without any issues. The 9-inch length gave me plenty of grip depth, and the plain finish cleaned up nicely.

Harper ★★★★★

The partial threading was exactly what I needed for a flange assembly, and the alloy steel feels rock solid. These bolts seated cleanly without any cross-threading, and the 25-pack is perfect for keeping spares around.
