Value Collection C39273 Plow Bolt 5/8-11 Unc Grade 8

Product Description

The VALUE COLLECTION C39273 is a Grade 8 alloy steel plow bolt with a 5/8-11 UNC thread size and 5 inches overall length (OAL). Plow bolts are a specialized fastener designed with a flat, countersunk head that sits flush with or below the surface of the mating component, preventing snagging and wear on earthmoving and agricultural equipment. The Grade 8 rating indicates high tensile strength, making this bolt suited for heavy-duty mechanical applications where joint integrity under dynamic load is critical. It ships uncoated, which is standard for applications where field coating or galvanizing will be applied on-site.

This plow bolt is used in agricultural, construction, and heavy equipment maintenance applications. Common installations include moldboards, cutting edges, wear plates, and other ground-engaging components on plows, graders, and earth scrapers. It is installed by equipment mechanics and maintenance technicians working on farm machinery or heavy construction equipment. The 5/8-11 UNC thread is a coarse-thread designation, compatible with standard Grade 8 hex nuts and flange nuts of the same thread specification.

Key Features

• Grade 8 alloy steel construction for high tensile strength under heavy mechanical load
• 5/8-11 UNC coarse thread for broad compatibility with standard nuts and tapped components
• 5 inches overall length suits typical wear-plate and moldboard fastening applications
• Flush countersunk head design prevents snagging on soil and debris
• Uncoated finish allows for field-applied coatings or use in pre-coated assemblies

Compatibility

Designed as a standard-pattern replacement plow bolt for agricultural and earthmoving equipment requiring a 5/8-11 UNC, Grade 8 fastener with a 5-inch overall length and a countersunk flat head.

Installation Notes

Installation is typically performed by equipment mechanics using standard hand tools and a torque wrench calibrated for Grade 8 fasteners at the 5/8-inch thread size. Always de-energize and safely support or block any equipment before accessing wear components. Use the appropriate Grade 8 nut and hardened washer where specified by the equipment manufacturer. Do not mix Grade 8 hardware with lower-grade nuts or substitute with ungraded fasteners.
