Part # 63574 – HEXLOCKNUT_3/4-10 GF FLANGE

HEXLOCKNUT_3/4-10 GF FLANGE

Western Part # 63574 is a Hex Flange Lock Nut with a 3/4-inch diameter and 10 threads per inch (UNC – Unified National Coarse). The “GF” designation signifies that this is a Grade F lock nut, indicating a high-strength fastener.

This lock nut features an integrated, non-spinning washer-like flange at its base. This flange distributes the clamping force over a wider area, eliminating the need for a separate washer and improving the load-bearing capability of the joint. The “lock nut” characteristic means it has a built-in mechanism designed to resist loosening when subjected to vibration, torque, or movement, which are prevalent in snow plowing operations. This locking feature can be achieved through various methods, such as a distorted thread or an integrated all-metal prevailing torque element. The 3/4-10 UNC threading ensures compatibility with corresponding 3/4-10 UNC bolts, providing a robust and secure connection.

In Western Snow Plow applications, a Grade F hex flange lock nut like Part # 63574 is used in the most critical structural connections where maintaining fastener tension is absolutely vital for safety and performance. These include:

• Securing major frame components: Where any loosening could compromise the plow’s structural integrity.
• High-stress pivot points: Ensuring that articulating parts remain securely fastened under dynamic loads.
• Mounting assemblies that experience significant vibration: Preventing fasteners from backing out in challenging conditions.

The Grade F rating ensures that this lock nut provides superior strength and enhanced prevailing torque properties, making it suitable for the most demanding joints on a snow plow. When used with a compatible high-strength bolt, it forms an extremely secure and vibration-resistant connection. Always refer to your Western Plow’s documentation and assembly diagrams to confirm that Part # 63574 is the correct lock nut for your specific application and to follow recommended torque specifications for proper installation.
