Description

This hex nut with 1/2-13 threads fastens components together on your machine. Replacing a worn, stripped, or missing nut restores a secure connection, helping prevent vibration, noise, and loosening during operation.

• Provides clamping force on a 1/2-13 bolt or threaded stud to hold parts securely
• Replace if threads are rounded, cross-threaded, rusted, or the nut will not tighten
• Helps reduce vibration, rattles, and shifting from loose hardware
• Useful any time original fasteners are lost during service or show damage

What's included: One hex nut (1/2-13) Install notes:

• Disconnect power and shut off gas/water supplies as applicable before servicing
• Support the assembly to prevent movement when removing or installing hardware
• Start threads by hand to avoid cross-threading; replace companion bolt/washer if damaged
• Tighten securely; refer to the service manual for any torque or threadlocker requirements
