Dorman 962-027 Prevailing Torque Lock Nut Grade Thread - 8 3/8-16

The Dorman 962-027 is a Grade 8 prevailing torque lock nut designed for high-strength fastening applications. This 3/8"-16 threaded lock nut features a nylon insert that creates resistance during installation, preventing loosening from vibration and torque without requiring additional locking devices.

Key Features:

• Grade 8 heat-treated steel construction for maximum tensile strength (150,000 PSI minimum)
• Prevailing torque design with nylon insert provides reliable locking action
• 3/8"-16 UNC thread size for standard coarse-thread applications
• Reusable design maintains locking capability through multiple installations
• Yellow zinc dichromate finish provides corrosion resistance
• Meets ASTM A194 and IFI specifications for dimensional accuracy

This lock nut is ideal for automotive, industrial, and heavy-duty applications where fastener integrity is critical. The prevailing torque design ensures the nut remains secure even in high-vibration environments, making it suitable for suspension components, engine mounts, drivetrain assemblies, and structural applications.
