Value Collection CAI503705000-050BX Carriage Bolt 3/8-16 5in

Product Description

The VALUE COLLECTION CAI503705000-050BX is a 3/8-16 carriage bolt with a 5-inch length under head and a square neck design. Made from Grade 5 steel with a zinc-plated finish, it provides reliable corrosion resistance for general fastening applications. The square neck seats flush into wood or soft material to prevent rotation during installation, eliminating the need for a wrench on the bolt end. This fastener is suitable for structural assembly work across construction, HVAC equipment mounting, plumbing support structures, and general mechanical applications. This item is sold in a minimum order quantity of 50 pieces per order.

This carriage bolt is appropriate for residential and light commercial fastening tasks where a clean, round-head profile is required on the finished face. Common applications include wood-to-wood connections, equipment frame assembly, and support bracket installation. The zinc plating provides adequate protection for interior and semi-exposed environments. Installers working on HVAC curb bases, plumbing hangers, or electrical equipment supports will find this bolt sized for standard 3/8-inch hardware configurations.

Key Features

• 3/8-16 UNC thread size for compatibility with standard 3/8-inch nuts and hardware
• 5-inch length under head accommodates thicker material stacks and multi-layer assemblies
• Square neck prevents bolt rotation during tightening without requiring a second wrench
• Grade 5 steel construction provides higher tensile strength than standard Grade 2 fasteners
• Zinc-plated finish offers corrosion resistance for interior and semi-protected installations
• Minimum order quantity of 50 suits job-site and shop stock requirements

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts and washers in wood, metal, and composite material fastening applications across construction and mechanical trades.

Installation Notes

Installation is performed by inserting the bolt through a pre-drilled hole and seating the square neck into the material to lock against rotation. Tighten the nut from the threaded end using an appropriately sized wrench or socket. Follow applicable building codes and structural load specifications when using fasteners in load-bearing assemblies. Do not exceed the rated tensile or shear load for Grade 5 fasteners as specified by applicable engineering or code requirements.
