Value Collection 244714 Carriage Bolt 3/8-16 2-1/2 in Grade 18-8

Product Description

The VALUE COLLECTION 244714 is a 3/8-16 carriage bolt with a 2-1/2 inch length under head, manufactured from Grade 18-8 stainless steel with an uncoated finish. The square neck design locks into material during installation, preventing rotation without requiring a wrench on the bolt head. This fastener follows Unified National Coarse (UNC) thread standards and is measured in the inch system. It is suited for structural assembly, outdoor fixtures, and applications where corrosion resistance is a priority. Tradespeople across plumbing, electrical, HVAC, and general construction reach for 18-8 stainless carriage bolts wherever moisture or chemical exposure is a concern.

This carriage bolt is appropriate for light structural connections in both residential and commercial settings. Common applications include equipment mounting, wood-to-metal connections, handrail assemblies, and outdoor brackets. The 18-8 stainless steel alloy provides solid resistance to rust and oxidation, making it a practical choice for exposed or wet environments. This fastener is sold individually but requires a minimum order quantity of 25 units.

Installation Notes

Carriage bolts are typically installed by a general tradesperson or mechanical contractor using a standard socket or wrench on the nut side. Insert the bolt through the pre-drilled hole so the square neck seats firmly into the material, then thread and tighten the nut from the opposite side. Do not apply a wrench to the round head. Ensure hole diameter matches the bolt shank to allow proper square neck seating and prevent spinning.
