Value Collection R52001180 Carriage Bolt 3/8-16 2.5 in

Product Description

The VALUE COLLECTION R52001180 is a 3/8-16 carriage bolt designed for general fastening applications requiring a flush, tamper-resistant head profile. Built from 1006/1050 grade steel with a galvanized zinc finish, this bolt resists corrosion in both indoor and moderate outdoor environments. The square neck beneath the dome head locks into wood or soft substrate to prevent rotation during nut tightening, eliminating the need for a second wrench on the bolt side. The shank is fully threaded at 2.5 inches under the head, conforming to ASME B18.5 standards. Trade contractors and maintenance professionals use this fastener in structural assemblies, decking, framing connections, and equipment mounting applications.

This carriage bolt is suited for residential and light commercial construction, wood framing, fencing, playground equipment, and general metalwork where a smooth bearing surface on one face is required. The UNC thread form (3/8-16) is the standard coarse-thread series, compatible with 3/8-16 hex nuts and threaded inserts. Fully threaded construction allows nut placement anywhere along the shank, adding flexibility in variable-thickness material stacks. Sold individually with a minimum order quantity of 50 pieces per order.

Key Features

• 3/8-16 UNC coarse thread for broad nut and insert compatibility
• Fully threaded shank provides flexible nut positioning along entire 2.5-inch length
• Square neck locks into substrate to prevent spin during installation
• Galvanized zinc finish provides corrosion resistance for indoor and light outdoor use
• Meets ASME B18.5 dimensional standards for carriage bolts
• 1006/1050 grade steel construction for reliable tensile strength in general fastening

Compatibility

Designed as a standard ASME B18.5 carriage bolt compatible with 3/8-16 UNC hex nuts, wing nuts, and threaded inserts in wood, composite, and soft metal substrates.

Installation Notes

Installation is performed by carpenters, ironworkers, and general contractors using a hammer to seat the square neck flush into the substrate, then threading the mating nut by hand before final torquing with a wrench. Always pre-drill a clearance hole sized to the bolt diameter to avoid splitting wood or damaging substrate material. Do not use an impact driver directly on the dome head. Follow applicable building code requirements for fastener spacing and load-bearing applications.
