Value Collection -32162-1 Carriage Bolt 5/16-18 3 in

Product Description

The VALUE COLLECTION -32162-1 is a 5/16-18 carriage bolt with a 3-inch length under head, designed for general fastening applications in wood, metal, and structural assemblies. It features a domed head and a square neck that bites into the material surface to prevent rotation during tightening, eliminating the need for a wrench or socket on the bolt end. Constructed from Grade 5 steel with a zinc-plated finish, this bolt offers solid tensile strength and basic corrosion resistance for indoor and protected outdoor installations. It is sold in a minimum order quantity of 100 pieces and is sized to Unified National Coarse (UNC) thread standards.

This carriage bolt is suited for residential and light commercial construction, furniture assembly, deck building, and general mechanical fabrication. The 5/16-18 UNC thread is a common size for through-bolt connections in wood framing, brackets, and equipment mounting. Installers working on decks, fences, or metal-to-wood connections will find this a standard fit for a wide range of structural fastening tasks. The zinc plating provides a measure of protection against moisture in semi-exposed environments.

Key Features

• Square neck locks into workpiece surface to prevent bolt rotation during nut tightening
• Grade 5 steel construction provides reliable tensile and shear strength for structural applications
• Zinc-plated finish offers basic corrosion resistance for semi-exposed environments
• 5/16-18 UNC thread is a widely compatible, industry-standard fastener size
• 3-inch length under head suits medium-depth through-bolt applications
• Sold in multiples of 100, appropriate for production or batch fastening work

Compatibility

Designed as a standard UNC carriage bolt for use in wood-to-wood and wood-to-metal fastening applications where a 5/16-18 thread and 3-inch grip length are specified.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance mechanics using standard hand tools. Drill a clean through-hole sized to the bolt shank diameter before insertion so the square neck seats properly and resists spin. Tighten the mating nut with a wrench to the specification called out in the applicable structural drawing or building code — do not over-torque, as this can deform the neck seat. Power down or de-energize any adjacent equipment before working in confined structural bays.
