Value Collection -32160-1 Carriage Bolt 5/16-18 Unc

Product Description

The VALUE COLLECTION -32160-1 is a 5/16-18 UNC carriage bolt designed for general fastening applications in metal and wood assemblies. It features a standard round dome head with a square neck that locks into the mounting surface to prevent rotation during tightening. The bolt measures 1 inch in length under the head and is fully threaded along its shank. Manufactured from Grade 5 steel with a zinc-plated clear chromate finish, it provides reliable mechanical strength and basic corrosion resistance. This fastener meets SAE J429 standards and is suited for use by contractors, fabricators, maintenance technicians, and tradespeople requiring a dependable UNC-thread carriage bolt.

This carriage bolt is appropriate for residential and light commercial construction, equipment assembly, structural framing connections, and general maintenance applications. The 5/16-18 UNC thread form is a standard coarse-thread configuration widely used in steel fabrication, wood framing hardware, HVAC equipment mounting, and machinery guarding. The zinc-plated clear chromate finish is suitable for dry indoor environments and mildly corrosive conditions. These bolts are typically installed using a standard wrench or socket on the mating nut, with the square neck seating into a correspondingly sized hole to resist spin-out.

Key Features

• 5/16-18 UNC fully threaded shank for maximum thread engagement
• Standard square neck prevents bolt rotation during nut tightening
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated clear chromate finish provides basic corrosion protection
• 1-inch length under head suits thin-to-medium material stack applications

Compatibility

Designed as a standard 5/16-18 UNC carriage bolt replacement compatible with any application requiring a Grade 5 fully threaded square-neck carriage bolt with a 1-inch length under head.

Installation Notes

Installation is performed by trades or maintenance personnel using hand tools. Before installation, ensure the receiving material has the correct hole diameter to seat the square neck and prevent rotation. A properly sized flat washer and hex nut should be used on the bearing side; tighten the nut to the torque specification required by the assembly design or applicable code. Do not use impact tools at full torque settings without verifying fastener grade compatibility.
