Value Collection 219374MSC Carriage Bolt 3/8-16 1-3/4 in

Product Description

The VALUE COLLECTION 219374MSC is a 3/8-16 partially threaded carriage bolt designed for general structural and mechanical fastening applications. It features a ribbed neck that locks into wood or soft material to prevent rotation during installation, eliminating the need for a secondary tool on the bolt side. The bolt is manufactured from Grade 5 steel and finished with a zinc trivalent chromate coating for corrosion resistance. Thread length is 1 inch on a 1-3/4 inch overall length under head. Thread standard is UNC, conforming to SAE J429.

This carriage bolt is suited for residential and light commercial construction, woodworking, framing connections, and equipment mounting where a flush, rounded head is required on the visible face. The ribbed neck design is particularly effective in timber-to-timber and timber-to-metal connections. Electricians, contractors, plumbers, and general tradespeople use this fastener when securing junction boxes, brackets, strut channel, and structural assemblies. The partial thread allows for clamping force across thicker material stacks.

Key Features

• 3/8-16 UNC thread for compatibility with standard nuts and hardware
• Ribbed neck prevents bolt rotation during tightening without a wrench on the bolt head
• Grade 5 steel construction provides reliable tensile and shear strength for structural use
• Zinc trivalent chromate finish delivers corrosion resistance in exposed or mildly humid environments
• Partially threaded shank with 1 inch of thread on 1-3/4 inch length under head
• Conforms to SAE J429 fastener standard

Compatibility

Designed as a standard UNC carriage bolt for use with 3/8-16 nuts and washers in structural wood, metal, and composite assemblies requiring a round-head low-profile fastener.

Installation Notes

Installation is performed by inserting the bolt through a pre-drilled hole so the ribbed neck seats into the material and prevents rotation. A standard wrench or socket is used on the nut side to draw the joint tight. Power down or de-energize any nearby electrical equipment before working in panel or enclosure assemblies. Follow applicable building codes and torque specifications defined by the structural design or engineer of record.
