Value Collection 781300PS Carriage Bolt 3/8-16 1-3/4 in

Product Description

The VALUE COLLECTION 781300PS is a 3/8-16 carriage bolt with a 1-3/4 inch length under head and a square neck, manufactured from Grade 18-8 stainless steel with a bright uncoated finish. Carriage bolts feature a domed head and a square neck that bites into the material being fastened, preventing rotation during installation without requiring a wrench on the bolt head. The 18-8 stainless steel construction provides solid corrosion resistance for general-purpose applications. This fastener follows inch measurement standards with a Unified National Coarse (UNC) thread form. It is installed by tradespeople, maintenance crews, and fabricators across mechanical, construction, and equipment assembly applications.

This carriage bolt is suited for light structural connections, equipment mounting, wood-to-metal assemblies, and general fastening tasks where corrosion resistance is a priority. The square neck design is appropriate for use in wood or soft substrates where the neck can seat flush and lock against rotation. Sold in multiples of 50 per order, this fastener is a standard stock item for shops and service fleets maintaining an inventory of common hardware sizes.

Key Features

• 3/8-16 UNC thread for broad nut and hardware compatibility
• 1-3/4 inch length under head provides adequate grip range for typical light structural connections
• Square neck locks against rotation in wood or compatible substrates during installation
• Grade 18-8 stainless steel construction resists corrosion in general-purpose environments

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt suitable for use with any standard 3/8-16 nut and compatible hardware in inch-standard fastening applications.

Installation Notes

Insert the bolt through the pre-drilled hole so the square neck seats fully into the substrate before applying a washer and nut to the threaded end. Tighten from the nut side only using the appropriate wrench or socket. Ensure the mating surface is clean and the hole diameter is matched to the bolt size to allow the square neck to lock properly. Follow applicable building or equipment codes for fastener specifications in structural or load-bearing installations.
