Value Collection 34628 Carriage Bolt 3/8-16 1-1/2 in Grade 2

Product Description

The VALUE COLLECTION 34628 is a Grade 2 carriage bolt with a 3/8-16 thread size and a 1-1/2 inch length. Carriage bolts feature a smooth, domed head and a square shoulder beneath it that bites into wood or soft materials to prevent rotation during tightening. This inch-system fastener is suited for general-purpose structural and assembly applications where a flush, snag-free head profile is required. Installers in construction, mechanical assembly, and trade work use these bolts for wood-to-wood and wood-to-metal connections.

This carriage bolt is appropriate for residential and light commercial construction, framing connections, deck building, fence assembly, and general equipment mounting. The 3/8-16 coarse thread provides solid engagement in wood and standard threaded hardware. At 1-1/2 inches in length, it suits thin stock and surface-mount applications where shorter fastener reach is needed.

Key Features

• 3/8-16 coarse thread for broad hardware compatibility
• 1-1/2 inch length suits thin-stock and surface-mount connections
• Grade 2 steel construction for general-purpose load requirements
• Domed head with square shoulder prevents spinning during installation
• Inch-system dimensions compatible with standard SAE hardware

Compatibility

Designed as a general-purpose replacement or supply bolt for applications requiring a 3/8-16 coarse thread carriage bolt in inch-system measurements. Compatible with standard 3/8-16 nuts and flat washers.

Installation Notes

Carriage bolts are typically installed by tradespeople and general contractors using a standard wrench or socket on the nut side while the square shoulder seats itself into the mating material. Always drill a correctly sized clearance hole before insertion to allow the square shoulder to seat flush. Do not apply torque directly to the domed head. Follow applicable building codes for fastener grade and spacing requirements in structural applications.
