Value Collection 781060PR Carriage Bolt 1/4-20 5/8in Ss

Product Description

The VALUE COLLECTION 781060PR is a 1/4-20 carriage bolt with a 5/8-inch length under head, designed for general fastening applications where a clean, rounded head and square neck are required. The square neck locks into wood or composite materials to prevent rotation during tightening without the need for a tool on the bolt head. Constructed from 18-8 stainless steel with a bright uncoated finish, this bolt offers solid corrosion resistance in wet, outdoor, or marine-adjacent environments. The thread standard is UNC (Unified National Coarse), measured under the head per standard inch fastener convention.

This carriage bolt is suited for light structural, framing, and general assembly tasks in residential and commercial settings. Common applications include wood-to-wood connections, fence and deck construction, equipment mounting, and utility installations where a flush or low-profile bolt head is needed. The 1/4-20 UNC thread pattern is widely used across HVAC equipment mounting, electrical enclosure assembly, and plumbing support structures. Stainless steel construction makes it appropriate for humid or outdoor service environments. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 5/8-inch length under head for shallow-stock fastening applications
• 18-8 stainless steel construction provides corrosion resistance in damp and outdoor environments
• Square neck prevents bolt rotation during nut tightening without requiring a wrench on the head
• Bright uncoated finish — no plating to chip, flake, or contribute to galvanic incompatibility with stainless hardware
• Inch measurement system, length measured under head per standard carriage bolt convention

Compatibility

Designed as a standard-dimension 1/4-20 UNC carriage bolt suitable for use with any 1/4-20 hex nut, flange nut, or compatible tapped component in wood, composite, or light-gauge panel assemblies.

Installation Notes

Install using a standard wrench or socket on the nut side — the square neck seats into the substrate to hold the bolt stationary. Ensure the receiving material is drilled or punched to the correct clearance diameter so the square neck seats fully before torquing the nut. When installing in stainless-to-stainless assemblies, apply an anti-seize compound to the threads to prevent galling. Fastener selection and installation in structural applications should conform to applicable building codes and engineering specifications.
