Value Collection 93338 Carriage Bolt 1/2-13 3 in Grade 18-8

Product Description

The VALUE COLLECTION 93338 is a 1/2-13 UNC carriage bolt with a 3-inch length under the head, designed for general fastening applications requiring a smooth, round head and a square neck that locks into place to prevent rotation during installation. Manufactured from Grade 18-8 stainless steel with an uncoated finish, this bolt offers reliable corrosion resistance in wet or outdoor environments. The square neck seats into a matching hole in the work material, allowing the nut to be tightened from one side without holding the bolt head. It is a standard inch-system fastener suited for structural, mechanical, and construction assemblies handled by tradespeople and maintenance professionals.

This carriage bolt is used in residential and commercial applications where a tamper-resistant, flush head appearance is required. Common installation scenarios include wood-to-wood connections, wood-to-metal framing, dock and deck construction, and equipment mounting. The 18-8 stainless steel material makes it appropriate for applications with exposure to moisture, mild chemicals, or outdoor conditions. Sold in multiples of 25 as a single package quantity, it is suited for stocking in trade supply bins or job-site kits.

Installation Notes

Installation is typically performed by general tradespeople, carpenters, ironworkers, or maintenance technicians using standard hand or power tools. Insert the bolt through a pre-drilled hole sized to seat the square neck, preventing rotation, then thread and tighten a nut from the opposite side. Torque to the assembly requirement specified by the project engineer or applicable structural standard. Follow applicable building codes and fastener specifications for the intended load-bearing application.
