Value Collection 37778 Plow Bolt 5/8-11 Unc Grade 8

Product Description

The VALUE COLLECTION 37778 is a Grade 8 alloy steel plow bolt with a 5/8-11 UNC thread size and a 2-inch overall length. The flat, countersunk head profile is designed to sit flush with mounting surfaces, preventing snagging and wear on blades, buckets, and ground-engaging equipment. The zinc yellow dichromate finish provides corrosion resistance for outdoor and heavy-use applications. This bolt meets SAE J429 standards and is suited for high-strength fastening in demanding environments. Installation is typically performed by equipment mechanics, fleet maintenance techs, or heavy-equipment service professionals.

Plow bolts are commonly used in earthmoving equipment, snow plows, grader blades, bulldozer cutting edges, and other ground-engaging attachments where a flush, recessed head fastener is required. The 5/8-11 UNC thread is a standard coarse thread pitch well suited to thick steel components and field replacement applications. The Grade 8 rating makes this bolt appropriate for high-load, high-vibration assemblies found in construction and municipal maintenance equipment.

Key Features

• Grade 8 alloy steel construction meets SAE J429 for high-strength fastening
• 5/8-11 UNC coarse thread for reliable engagement in heavy steel components
• 2-inch overall length suits standard blade and bucket attachment profiles
• Zinc yellow dichromate finish resists corrosion in outdoor and wet conditions
• Flush countersunk head design minimizes material hang-up on ground-engaging surfaces

Compatibility

Designed as a standard-fitment plow bolt for ground-engaging equipment attachments requiring a 5/8-11 UNC Grade 8 fastener with a 2-inch overall length, including snow plow blades, grader cutting edges, and bulldozer blade assemblies.

Installation Notes

Installation is typically performed by equipment mechanics using standard hand tools and impact wrenches. Always power down and de-energize or relieve hydraulic pressure from the equipment before servicing blade or bucket attachments. Use a properly rated nut and hardened washer matched to Grade 8 specifications. Follow equipment manufacturer torque sequences when replacing multiple fasteners on a blade assembly.
