Value Collection 37691 Plow Bolt 1/2-13 Unc Grade 8 Alloy Steel

Product Description

The VALUE COLLECTION 37691 is a Grade 8 alloy steel plow bolt with a 1/2-13 UNC thread size and a 1-1/2 inch overall length (OAL). Plow bolts feature a flat, countersunk head that sits flush with the mating surface, making them a standard fastener choice in heavy equipment, earthmoving machinery, and agricultural implements where a smooth wear surface is required. The uncoated finish suits applications where the bolt will be field-replaced frequently or where a secondary coating will be applied. Licensed tradespeople, equipment mechanics, and maintenance technicians working on heavy-duty machinery are the primary installers of this fastener type.

This plow bolt is suited for use in high-stress fastening applications on construction equipment, agricultural machinery, and similar heavy-duty assemblies. Grade 8 alloy steel provides the tensile strength required for demanding mechanical connections subject to vibration and load cycling. The 1/2-13 UNC thread is one of the most common coarse-thread sizes in North American equipment, making this bolt broadly applicable across a wide range of repair and maintenance scenarios.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding applications
• 1/2-13 UNC coarse thread for broad compatibility with standard North American hardware
• 1-1/2 inch OAL suits compact fastening locations in equipment assemblies
• Flush-seating countersunk head design keeps mating surfaces smooth
• Uncoated finish allows for field replacement or secondary coating as needed
• Sold in packages of 25 units to support service and maintenance stock

Compatibility

Designed as an OEM-style replacement fastener for heavy equipment, agricultural machinery, and earthmoving applications requiring a 1/2-13 UNC Grade 8 plow bolt with a 1-1/2 inch OAL.

Installation Notes

Installation is typically performed by equipment mechanics or maintenance technicians following the equipment manufacturer's service procedures. Always de-energize, lock out, and tag out any equipment before replacing structural fasteners. Use appropriate hand or power tools rated for Grade 8 fasteners, and follow the manufacturer's torque specifications for the specific equipment being serviced. Inspect mating surfaces and threaded holes for wear or damage before installing new hardware.
