Value Collection -32171-2 Carriage Bolt 5/8-11 6 in Grade 5

Product Description

The VALUE COLLECTION -32171-2 is a 5/8-11 carriage bolt with a 6-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish. Carriage bolts use a domed head and square neck that bites into the mating material to prevent rotation during installation, eliminating the need for a wrench on the bolt head. This fastener follows Unified National Coarse (UNC) thread standards and is sized for structural and general mechanical assembly applications where a clean, tool-free head profile is required. Plumbers, pipefitters, electricians, and general tradespeople reach for this bolt when connecting wood, metal brackets, or structural members in equipment installations.

The -32171-2 carriage bolt is suited for residential and light commercial trade work including equipment mounting, structural bracing, unistrut connections, and panel or bracket assembly. The zinc-plated finish provides baseline corrosion resistance for indoor and sheltered outdoor applications. Each package contains 25 bolts, making it practical for installations requiring multiple fasteners of the same size.

Key Features

• 5/8-11 UNC thread for broad compatibility with standard nuts and tapped hardware
• 6-inch length under head accommodates thicker material stacks and spacer assemblies
• Grade 5 steel construction provides higher tensile strength than standard Grade 2 fasteners
• Square neck under the domed head locks against the mating surface to resist spinning during torque application
• Zinc-plated finish for corrosion resistance in dry and sheltered environments
• Sold in a 25-count package to support multi-bolt installations

Compatibility

Designed as a standard UNC carriage bolt for use with 5/8-11 hex nuts, washers, and tapped structural hardware in general trade and mechanical assembly applications.

Installation Notes

Carriage bolts are typically installed by a licensed tradesperson or experienced mechanic using a standard socket or wrench on the nut side only. Insert the bolt through the pre-drilled hole and seat the square neck firmly into the material before applying torque to the nut. Do not use an impact driver directly on the domed head. Follow applicable building codes and equipment manufacturer torque specifications when used in structural or load-bearing connections.
