Auveco 5254 #14 External Tooth Lock Washers

The Auveco 5254 is a #14 external tooth lock washer designed to prevent fastener loosening through vibration and movement. This washer features external serrations that bite into both the fastener head and mounting surface, creating a secure mechanical lock that resists backing out under stress.

Key Features:

• External tooth design provides superior gripping action
• #14 size for use with #14 screws and bolts
• Serrated teeth create multiple contact points for enhanced holding power
• Prevents loosening caused by vibration and thermal cycling
• Ideal for automotive, industrial, and general mechanical applications

External tooth lock washers are preferred in applications where the washer needs to grip both the fastener and the work surface. The outward-facing teeth distribute clamping force while preventing rotation, making them essential for securing critical fasteners in vehicles, machinery, and equipment.
