Value Collection 204155MSC Plow Bolt 1/2-13 Unc Grade 5

Product Description

The VALUE COLLECTION 204155MSC is a Grade 5 steel plow bolt with a 1/2-13 UNC thread size and an overall length of 2.5 inches. Plow bolts feature a flat, countersunk head that sits flush with the mating surface, preventing material buildup and reducing wear on equipment. This bolt is uncoated and manufactured to ASME/ANSI B18.9 and SAE J429 standards, making it a reliable choice for heavy-duty fastening applications. It is suited for use by equipment mechanics, field technicians, and maintenance crews who work on earthmoving or agricultural machinery.

Plow bolts of this type are commonly used in blade and cutting edge assemblies on graders, bulldozers, scrapers, and similar earthmoving equipment. The flush-head design is essential in these applications because protruding fastener heads would be subject to direct ground contact and rapid wear. The 1/2-13 UNC thread form is a standard coarse-thread configuration that seats reliably in both new and field-replaced blade stock.

Key Features

• Grade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fastening
• 1/2-13 UNC coarse thread for reliable engagement in blade and cutting edge stock
• 2.5-inch overall length suits standard blade thickness applications
• Flush countersunk head design per ASME/ANSI B18.9 prevents head exposure to ground wear
• Uncoated finish — suitable for applications where galvanic compatibility or field welding is a consideration

Compatibility

Designed as an OEM-style replacement fastener for use in blade and cutting edge assemblies on earthmoving and agricultural equipment requiring 1/2-13 UNC Grade 5 plow bolts per ASME/ANSI B18.9.

Installation Notes

Installation is typically performed by equipment mechanics using standard hand tools and torque wrenches rated for Grade 5 fasteners. Always power down and de-energize or depressurize the equipment before servicing blade assemblies. Use a hardened flat washer and compatible Grade 5 nut on the back side of the blade stock. Do not substitute a standard hex-head cap screw for a plow bolt in flush-mount applications, as head geometry is not interchangeable.
