Value Collection 781624PS Carriage Bolt 3/8-16 10in Ss

Product Description

The VALUE COLLECTION 781624PS is a 3/8-16 carriage bolt with a 10-inch length under head, designed for fastening applications that require a clean, non-rotating head profile. The square neck beneath the domed head bites into the material during tightening, preventing the bolt from spinning without requiring tool access to the bolt head. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener offers solid corrosion resistance in wet, outdoor, and light chemical environments. It is suited for use by contractors, maintenance technicians, and tradespeople working with wood, metal, or structural assemblies where a flush, tamper-resistant head is required.

This carriage bolt is commonly used in residential and light commercial construction, dock and deck framing, equipment mounting, and general structural connections. The 3/8-16 UNC thread standard is widely compatible with standard hex nuts and washers. At 10 inches in length under head, this bolt suits thick-material or through-bolt applications where shorter fasteners cannot span the joint. Installers working in marine, poolside, or outdoor environments will benefit from the 18-8 stainless steel construction, which resists rust and oxidation better than standard zinc-plated carbon steel fasteners.

Key Features

• 3/8-16 UNC thread for compatibility with standard nuts and threaded hardware
• 10-inch length under head accommodates thick-stock and through-bolt installations
• Square neck prevents bolt rotation during nut tightening without back-tool access
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Bright, uncoated finish maintains dimensional accuracy and thread fit

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt compatible with matching hex nuts, coupling nuts, and flat or fender washers following inch-standard fastener specifications.

Installation Notes

Installation is typically performed by carpenters, contractors, or maintenance technicians using standard hand or power tools. Drill a clearance hole sized for the bolt shank, insert the bolt from the face side, and seat the square neck into the material before threading the nut. Apply torque to the nut only — the square neck resists head rotation. Follow applicable building codes and structural specifications for joint design, load ratings, and fastener spacing.
