S-90911A677 7/16"-14 x 2" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional Tensile Strength – With 120,000 psi tensile strength, these bolts withstand extreme loads, reducing the risk of fastener failure in demanding applications.
• Superior Corrosion Resistance – Zinc-plated steel construction provides a durable barrier against rust and environmental wear, extending service life in outdoor or harsh conditions.
• Secure Anti-Rotation Locking – The square neck design prevents the bolt from turning during installation, ensuring a stable and reliable fit without the need for additional locking devices.
• Optimized Thread Engagement – Fully threaded 7/16"-14 UNC coarse threads and Class 2A fit enable quick assembly and consistent clamping force, minimizing installation time.
• High Hardness for Durability – Rockwell C25 hardness offers excellent resistance to deformation and wear, maintaining bolt integrity under repetitive stress.
• Flush Mounting Capability – The 82° countersink angle and flat head allow the bolt to sit flush with surfaces, preventing snagging and improving safety in moving machinery.
• Reliable Industrial Standards Compliance – Meets ASME B18.9 and SAE J429 specifications, ensuring consistent quality and performance for industrial and agricultural equipment.

Professional Applications & Engineering Value

Engineered for heavy-duty applications, this Grade 5 Plow Bolt delivers reliable performance in agricultural, construction, and industrial machinery. The zinc-plated steel material combats corrosion, which is critical for equipment exposed to moisture, soil, and chemicals. Its fully threaded UNC coarse thread design ensures rapid installation and high vibration resistance, reducing maintenance downtime. The square neck effectively locks the bolt in place, preventing rotation during torque application—a common issue in high-stress assemblies. With an 82° countersink angle and flat head, it provides a smooth, flush finish that minimizes protrusion risks on plow blades, tillage tools, and conveyor systems. These features address key engineering challenges like fastener loosening, corrosion-induced failure, and assembly efficiency, making it a trusted choice for durable fastening solutions.
