Value Collection 489026PR Carriage Bolt 1/4-20 2-1/2 in Square Neck

Product Description

The VALUE COLLECTION 489026PR is a 1/4-20 UNC carriage bolt with a 2-1/2 inch length under head and a square neck design. Manufactured from Grade 2 steel with a zinc-plated finish, it meets ASTM A307 standards for general-purpose fastening applications. The square neck seats flush into pre-drilled square holes to prevent rotation during installation, eliminating the need for a wrench on the bolt head. This fastener is used by contractors, millwrights, and general tradespeople in a wide range of structural and mechanical assemblies.

This carriage bolt is suited for light-to-medium-duty fastening in wood-to-wood and wood-to-metal connections. Common applications include framing, fence construction, equipment mounting, and general structural assembly in residential and light commercial settings. The zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor use. Sold in multiples of 100, this bolt is appropriate for production assembly or job-site supply where consistent fastener stock is required.

Compatibility

Designed as a standard inch-series carriage bolt for use with 1/4-20 UNC hex nuts and washers in general structural and mechanical fastening applications.

Installation Notes

Installation is typically performed by carpenters, contractors, or general tradespeople using a standard wrench or socket on the mating nut. Insert the bolt through a pre-drilled hole so the square neck seats fully into the material to prevent spinning before applying the nut. Do not overdrive or impact-set the bolt head, as this may strip the square neck seat. Follow applicable building codes and fastener load tables for structural applications.
