Value Collection 219384MSC Carriage Bolt 3/8-16 2 in Ribbed Neck

Product Description

The VALUE COLLECTION 219384MSC is a 3/8-16 carriage bolt designed for general fastening applications in wood-to-wood and wood-to-metal assemblies. The ribbed neck locks the bolt in place as it is driven through a pre-drilled hole, preventing rotation without requiring a wrench on the bolt head. Manufactured from Grade 5 steel with a clear zinc chromate finish, this bolt offers solid corrosion resistance for indoor and light outdoor use. At 2 inches in length under head with 1 inch of UNC partial threading, it suits a wide range of standard structural and mechanical connections. It weighs 0.02 pounds per unit.

This carriage bolt is appropriate for residential and light commercial construction, woodworking, and equipment fabrication where a smooth, self-locking fastener is required. Common install scenarios include deck framing, fence hardware, jig assembly, and machinery mounting where the domed head must sit flush against the surface. The inch-system sizing and UNC thread form make it compatible with standard inch-series nuts and hardware. It conforms to SAE J429 standards, making it suitable for structural fastening applications that call out that specification.

Compatibility

Designed as a standard inch-series carriage bolt for use with 3/8-16 UNC hex nuts and washers in wood, metal, and composite material assemblies conforming to SAE J429 fastener specifications.

Installation Notes

Installation is typically performed by carpenters, millwrights, or general contractors using a hammer to seat the ribbed neck flush into a pre-drilled hole, then tightening the mating nut with a standard wrench or socket set. Power down or de-energize any equipment before fastening into electrical enclosures or panels. Verify hole diameter is sized correctly for the shank to ensure the ribbed neck engages properly and does not spin. Follow applicable structural codes when using fasteners in load-bearing connections.
