USA INDUSTRIALS Carriage Bolt: Square Neck, 1/2"-13 Thread Size, 9 in lg, Steel, Grade 2

A Grade 2 steel square neck carriage bolt is used to fasten metal to wood or metal to metal in construction, machinery assembly, and structural applications. The square neck prevents rotation during tightening, making it ideal for bolting down equipment, securing framing, and general industrial fastening where a flush, rounded head is desired.

The USA INDUSTRIALS ZBOLT-780 carriage bolt has a 1/2"-13 thread size, is 9 inches long, and is made from Grade 2 steel. It features a square neck to prevent spinning during installation and is sold in a pack of 5. This bolt is suitable for moderate-strength fastening in non-critical structural connections.

To install a square neck carriage bolt, drill a hole matching the bolt diameter. Insert the bolt through the hole so the square neck seats into the material, preventing rotation. Tighten a nut and washer on the opposite side with a wrench. For wood, pre-drill to avoid splitting. Use a torque wrench to avoid over-tightening Grade 2 steel.
