Value Collection 93314 Carriage Bolt 5/16-18 2.5 in Stainless

Product Description

The VALUE COLLECTION 93314 is a 5/16-18 UNC carriage bolt with a 2-1/2 inch length under head and a square neck drive style. Manufactured from Grade 18-8 stainless steel with an uncoated finish, this fastener delivers solid corrosion resistance for general-purpose structural and mechanical assemblies. The square neck seats flush into a pre-drilled hole and locks against rotation during installation, eliminating the need for a wrench or socket on the bolt head. Tradespeople in construction, plumbing, and general fabrication reach for 18-8 stainless carriage bolts wherever moisture exposure or mild corrosive environments are a concern.

This carriage bolt is suited for light structural connections, wood-to-wood and wood-to-metal assemblies, brackets, rails, and general fastening applications where corrosion resistance is required. The UNC thread form is the standard inch-series coarse thread used throughout North American construction and manufacturing. Sold individually, with a minimum order quantity of 25 pieces, making it appropriate for both small repairs and larger installation projects requiring consistent, matched hardware.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance tradespeople using a standard wrench or socket on the mating nut. Drill the through-hole to match the bolt shank diameter so the square neck seats fully and prevents rotation before torquing the nut. Do not overtighten stainless steel fasteners — 18-8 stainless is susceptible to galling; apply an appropriate anti-seize compound to the threads if specified by the application. Follow applicable structural fastening codes for the assembly type.
