Value Collection 242364 Carriage Bolt 5/16-18 2in Square Neck Ss

Product Description

The VALUE COLLECTION 242364 is a 5/16-18 carriage bolt with a 2-inch length under head, manufactured from 18-8 stainless steel in an uncoated, bright finish. The square neck design locks the bolt in place against the material being fastened, preventing rotation during nut tightening without requiring a wrench on the bolt head. This fastener follows Unified National Coarse (UNC) thread standards and is measured using the inch system. It is suited for structural and mechanical assemblies where corrosion resistance and reliable clamping force are required. Electricians, plumbers, HVAC technicians, and general tradespeople commonly use carriage bolts for panel mounting, equipment securing, and structural connections.

This carriage bolt is appropriate for use in both residential and light commercial applications where stainless steel corrosion resistance is needed. Typical install scenarios include outdoor equipment mounting, pool and spa hardware, HVAC equipment support structures, and any fastening application where galvanic corrosion or moisture exposure is a concern. The 18-8 stainless steel alloy provides good resistance to rust and oxidation without additional coating.

Key Features

• 5/16-18 UNC thread size for broad compatibility with standard hex nuts and inserts
• 2-inch length under head for medium-depth fastening applications
• Square neck locks bolt against workpiece, preventing spin-out during installation
• 18-8 stainless steel construction resists corrosion in wet or outdoor environments
• Bright uncoated finish with no plating or coating that could flake or delaminate

Compatibility

Designed as a standard UNC carriage bolt for use with 5/16-18 hex nuts, wing nuts, and threaded inserts in wood, metal, and composite assemblies.

Installation Notes

Insert the bolt through a pre-drilled hole sized to allow the square neck to seat flush and lock against the material. Tighten the mating nut using a standard wrench or socket; the square neck eliminates the need to hold the bolt head. Power down or de-energize any equipment before fastening near electrical components. Minimum order quantity for this item is 25 pieces.
