Value Collection 238094MSC Carriage Bolt 3/8-16 1-1/2 in Grade 5

Product Description

The VALUE COLLECTION 238094MSC is a Grade 5 steel carriage bolt designed for general structural fastening applications. With a 3/8-16 UNC thread and a 1-1/2 inch length under head, this bolt features a square neck that locks into place as the fastener is driven, preventing rotation without a wrench on the bolt head. The shank is fully threaded, maximizing thread engagement across the full usable length. A clear zinc chromate finish provides basic corrosion resistance suitable for indoor and light-duty applications. Meeting SAE J429 standards, this bolt delivers the mechanical strength expected in trade and production fastening work.

This carriage bolt is used in wood-to-wood, wood-to-metal, and light structural assemblies common in HVAC equipment mounting, electrical panel framing, plumbing support brackets, and general construction. The square neck is suited for installation through pre-drilled holes where the neck seats flush and resists spin-out during nut tightening. Sold individually per the package quantity, with a minimum order quantity of 100 pieces, making it appropriate for contractors and tradespeople stocking fasteners for ongoing fieldwork or production assembly.

Compatibility

Designed as a standard UNC carriage bolt for use with 3/8-16 nuts and washers in general structural and equipment-mounting fastening applications.

Installation Notes

Installation is typically performed by carpenters, ironworkers, or trade technicians using a standard wrench or socket on the nut side. Always drill the appropriate clearance hole so the square neck seats fully and resists rotation before applying torque to the nut. Follow applicable structural and mechanical codes for fastener selection and spacing in load-bearing assemblies.
