M6 External Tooth Lock Washers | Zinc Plated | Bag of 100

Ensure your critical bolted assemblies remain tight and secure with this bulk pack of M6 external tooth lock washers. Manufactured from hardened steel and finished with a bright zinc plating, these washers are designed to provide superior vibration resistance, preventing nuts and bolts from loosening under stress, shock, or dynamic loads.

Key Specifications:

• Nominal Size: M6 (for 6mm bolts)

• Type: External Tooth Lock Washer (Star Washer)

• Material: Hardened Steel

• Finish: Bright Zinc Plated (corrosion resistant)

• Pack Quantity: 100 Pieces

How They Work & Core Benefits:

• Bite-In, Vibration-Proof Locking: The sharp, external teeth bite into both the bolt head/nut and the mating surface, creating a strong, serrated grip that resists rotational loosening caused by vibration and thermal cycling.

• Excellent Electrical Grounding: The biting teeth cut through oxidation and paint, creating a solid metal-to-metal contact ideal for establishing reliable electrical grounding paths in automotive, electrical, and machinery panels.

• Distributes Load: Acts as a hardened flat washer, helping to distribute the load and protect softer surfaces from damage.

• Corrosion Resistance: The zinc plating provides a protective layer against rust and oxidation in standard environments.

Primary Applications:

• Automotive & Machinery: Essential for engine components, brackets, exhaust systems, and any assembly subject to constant vibration.

• Electrical Panels & Enclosures: Used to secure terminal blocks, DIN rails, and components where a solid electrical ground is required.

• Metal Fabrication & Structural Joints: Ideal for securing structural brackets, frames, and equipment where joint integrity is critical.

• General Industrial Maintenance: A standard component for repairing and maintaining equipment, vehicles, and machinery.
