Value Collection 781090PR Carriage Bolt 1/4-20 1-3/4 in Square Neck

Product Description

The VALUE COLLECTION 781090PR is a 1/4-20 carriage bolt with a 1-3/4 inch length under head, manufactured from 18-8 stainless steel in a bright, uncoated finish. Carriage bolts feature a smooth domed head and a square neck directly beneath it that pulls into the material being fastened, preventing the bolt from spinning during nut installation. This bolt follows the Unified National Coarse (UNC) thread standard and is measured by length under head per inch-system conventions. The 18-8 stainless steel construction provides solid corrosion resistance for general-purpose fastening tasks in both indoor and outdoor environments. Trade professionals and maintenance technicians use this fastener wherever a clean, tamper-resistant head profile and corrosion-resistant material are required.

This carriage bolt is suited for wood-to-wood and wood-to-metal connections across a wide range of light structural, maintenance, and equipment assembly applications. It is commonly installed in residential construction, equipment mounting, and outdoor fixture assembly where stainless steel is specified for moisture or corrosion exposure. Sold individually per package with a minimum order quantity of 100 units, making it appropriate for project-quantity procurement by contractors and maintenance crews.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard 1/4-inch nuts and inserts
• 1-3/4 inch length under head for precise grip-length selection
• Square neck locks into substrate to prevent rotation during fastening
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Bright, uncoated finish maintains material-true appearance with no coating thickness to account for
• Inch-system dimensions for direct compatibility with standard US fastener tooling

Compatibility

Designed as a standard UNC carriage bolt for use with 1/4-20 nuts, washers, and threaded inserts in wood, metal, and composite substrates where a domed, non-removable head profile is required.

Installation Notes

Carriage bolts are typically installed by general contractors, maintenance technicians, or trade professionals using standard hand or power tools. Insert the bolt through a pre-drilled hole sized to allow the square neck to seat flush with the material surface, then apply a washer and nut from the opposite side. Use a standard wrench or socket on the nut only — do not apply torque to the head. Power down or de-energize any associated equipment before fastener work on live assemblies.
