Value Collection 37716 Plow Bolt 7/8-9 Unc 3 in Grade 8

Product Description

The VALUE COLLECTION 37716 is a Grade 8 alloy steel plow bolt with a 7/8-9 UNC thread size and a 3-inch overall length. Plow bolts are designed with a flat, countersunk head that sits flush with or below the mating surface, preventing snagging and wear in demanding applications. The uncoated finish is standard for Grade 8 hardware where post-installation coating or galvanic compatibility is managed in the field. This fastener is suited for heavy-duty agricultural, construction, and earth-moving equipment assembly and repair work performed by equipment mechanics and field service technicians.

This plow bolt is used in applications where a flush head profile is required to protect cutting edges, wear plates, moldboards, and similar ground-engaging components from interference and accelerated wear. The 7/8-9 UNC coarse thread pitch provides strong engagement in structural connections subject to vibration and impact loading. Its Grade 8 rating makes it appropriate for high-stress joints in agricultural equipment, road graders, bulldozers, scrapers, and similar heavy machinery.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding applications
• 7/8-9 UNC coarse thread for reliable engagement under vibration and impact
• 3-inch overall length suits standard wear plate and moldboard fastening requirements
• Flush countersunk head design minimizes snagging on ground-engaging surfaces
• Uncoated finish for compatibility with field-applied coatings or plated nut pairings

Compatibility

Designed as a standard 7/8-9 UNC Grade 8 plow bolt for use with compatible heavy hex or plow bolt nuts in agricultural and construction equipment fastening applications.

Installation Notes

Installation is performed by equipment mechanics using standard impact wrenches or torque wrenches appropriate to Grade 8 fastener specifications. Ensure mating surfaces are clean and free of debris before seating the bolt head flush. Use a Grade 8 or equivalent rated nut and hardened washer where required by the equipment manufacturer. Always de-energize and safely support equipment before performing fastener replacement on wear plates or ground-engaging components.
