Performance Eng GNLW Lock Washer Tanged 2.5in Green

The Performance Eng GNLW is a tanged lock washer designed for high-performance applications requiring secure fastening. This 2.5-inch diameter lock washer features integrated tangs that bite into both the fastener and the mounting surface to prevent loosening from vibration and torque.

Key Features:

• 2.5-inch outer diameter for use with large bolts and studs
• Tanged design provides superior anti-rotation protection
• Green coating for corrosion resistance and easy identification
• Ideal for racing, automotive, and high-vibration applications
• Prevents fastener loosening under extreme conditions

Tanged lock washers work by having external tabs or tangs that are bent up after installation to lock the fastener in place mechanically. This design is commonly used in performance engines, transmissions, and suspension components where conventional lock washers may not provide adequate security.
