A Complete Guide to Plow Bolts

What are Plow Bolts?

Plow bolts are heavy-duty fasteners with a flat, countersunk head, a square neck, and a uniform thread pitch. These features allow the bolt to sit flush with the surface once installed, creating a smooth finish that reduces wear and prevents snagging.

Plow bolts are used in equipment where surface clearance and structural strength are critical. They are commonly found in bulldozers, graders, snowplows, and other heavy machinery. Their design helps increase the durability of the joint and keeps high-impact components securely fastened under stress.

What are Plow Bolts Used For?

Plow bolts are used in equipment that requires strong, flush-mounted fasteners, including:

• Construction Equipment: Plow bolts are installed in bulldozers, excavators, and graders. Their flush head prevents snagging and wear in high-contact areas like blades and cutting edges.

• Farming Machinery: These bolts secure components in plows, tillers, and harvesters. The countersunk head helps protect soil-facing parts from damage and ensures a smooth operation.

• Heavy Machinery: Plow bolts are used in loaders, mining equipment, and large transport systems. Their tight fit and flush finish help maintain structural integrity under repeated impact and vibration.

In each of these applications, plow bolts provide a stable connection that holds under extreme conditions while preserving surface performance.

The Key Features and Benefits of Plow Bolts

Plow bolts are built for strength, stability, and surface protection in heavy-duty applications.

• Flat Countersunk Head: The head sits flush with the material surface. This creates a smooth finish that prevents catching, reduces wear, and supports a longer service life in high-friction areas.

• Square Neck: The square neck locks into the material during installation. This stops the bolt from turning, allowing for a fast, secure fit with one-sided access.

• Unified Thread Pitch: Plow bolts feature a consistent, standardized thread pattern. This ensures compatibility with matching nuts and promotes even load distribution across the fastener.

These features make plow bolts ideal for equipment that experiences high impact, vibration, and surface contact.

The Different Types of Plow Bolts Sold by Springs Fastener

Springs Fastener supplies high-strength plow bolts for use in construction, agriculture, and industrial equipment. We offer multiple grades and finishes to meet different load and environmental requirements.

• Grade 5 Plow Bolts: Grade 5 plow bolts provide medium-strength fastening for general-purpose use. They are suitable for most machinery applications that require reliable tension and moderate impact resistance.

• Grade 5 Plow Bolts with Zinc Finish: These bolts offer the same strength as standard Grade 5 bolts, with added corrosion protection. The zinc coating helps extend bolt life in wet or corrosive environments such as outdoor or agricultural settings.

• Grade 8 Plow Bolts: Grade 8 plow bolts are designed for high-stress applications. Made from hardened alloy steel, they provide superior strength and wear resistance, making them ideal for heavy equipment and high-load connections.

Each type is available in a range of sizes and thread patterns to fit your specific equipment and fastening needs. Not finding what you are looking for? Contact us or request a quote to get started.
