Stainless Steel Serrated External Teeth Lock Washer

Stainless Steel Serrated External Teeth Lock Washer – Anti-Vibration Locking Washer for Electrical, Automotive & Industrial Fastening | High-Grip Washers in UAE

High performance in fastening, serrated external lock washer teeth can deliver maximum locking power and resist vibration while keeping a long-term holding strength. Serrated teeth that face outwards dig in, preventing nuts and bolts from loosening by rotational, impact, or mechanical vibration.

Manufactured from stainless steel of a high grade (SS 304 / SS 316), this lock washer is specially made for high-speed machinery, electrical terminals, automotive assemblies, HVAC systems, and structural joints. It is, however, for high-stressed conditions and engineers demanding secure, maintenance-free fastening.

✅ Key Features

1. Aggressive External Serrations
   Teeth on the outer rim dig into the connected surfaces to provide superior anti-loosening action, especially under vibration or thermal expansion.

2. Stainless Steel Construction
   SS 304 or SS 316, providing excellent corrosion resistance, high tensile strength, and a superior service life in environments surrounding indoors and outdoors.

3. Non-Slip Performance
   Prevents back-off of fasteners in assemblies subject to dynamic loads, movement, or high-frequency vibration.

4. High Surface Pressure
   Even distribution of pressure and bolt loosening and surface shift or wear prevention.

5. Reusable and Maintenance Free
   Designed to allow reuse in demanding environments without losing grip.
