Value Collection 781366PS Carriage Bolt 3/8-16 5in Square Neck

Product Description

The VALUE COLLECTION 781366PS is a 3/8-16 carriage bolt with a 5-inch length under the head and a square neck, manufactured from 18-8 stainless steel with a bright, uncoated finish. The square neck seats flush into the work material to resist rotation during fastening, eliminating the need for a wrench on the bolt head. At 0.1467 pounds, this fastener is well-suited for structural and mechanical assembly work where corrosion resistance is a priority. The 18-8 stainless steel composition provides solid resistance to rust and oxidation in wet or outdoor environments. Installers in plumbing, HVAC fabrication, electrical enclosure work, and general trade construction rely on this bolt for reliable, low-maintenance fastening.

This carriage bolt is used in a wide range of trade and industrial applications where a corrosion-resistant, flush-seating fastener is required. Typical installations include outdoor equipment mounting, pool and spa equipment frames, HVAC unit stands, plumbing fixture assemblies, and structural connections exposed to moisture. The UNC thread standard ensures broad compatibility with standard 3/8-16 nuts and threaded hardware. This part is sold individually but must be ordered in multiples of 10.

Key Features

• 3/8-16 UNC thread for compatibility with standard nuts and threaded hardware
• 5-inch length under head for deeper material penetration and longer grip range
• Square neck design prevents bolt rotation during tightening without a back wrench
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Bright uncoated finish with no surface treatment that could affect dimensional tolerances
• Inch system of measurement for straightforward integration with standard Imperial hardware

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt suitable for use with any compatible 3/8-16 nut and appropriately sized hardware in inch-standard fastening applications.

Installation Notes

Installation is performed by tradespeople during equipment assembly, structural framing, or fixture mounting tasks. Before installation, verify that the receiving material has a properly sized hole to allow the square neck to seat and lock without spinning. Use a standard wrench or socket on the nut side to tighten; no tool should be needed on the bolt head once the neck is seated. Follow applicable mechanical and structural codes for fastener torque and material compatibility when used in load-bearing or code-governed assemblies.
