Hillman Fasteners 240192 Carriage Bolt 3/8-16x6 in 50 Pack

Product Description

The HILLMAN FASTENERS 240192 is a 3/8-16 x 6 inch steel carriage bolt with a round head, square neck, and coarse thread pattern. Carriage bolts are designed for through-bolt fastening applications where a smooth, finished head face is required on one side of the assembly. The square neck seats into the work material to prevent rotation during tightening, eliminating the need for a wrench on the bolt head. This pack contains 50 bolts, making it practical for production work, framing, decking, and structural fastening tasks handled by contractors and skilled tradespeople.

This carriage bolt is suited for general construction, wood-to-wood, and wood-to-metal fastening where a 3/8-16 coarse thread pattern is specified. Common applications include deck framing, playground equipment, dock construction, and timber connections. The 6 inch length provides adequate grip for thicker material assemblies. The pack quantity of 50 supports jobs requiring multiple fasteners of the same specification.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance tradespeople using a standard wrench or socket on the nut side. Drill a clearance hole sized for a 3/8 inch bolt through the mating materials before inserting the bolt. Seat the square neck fully into the material to prevent rotation, then apply a washer and nut and tighten from the nut side only. Follow applicable building codes and fastener spacing requirements for structural connections.
