Lock Washers

Lock washers are specialised fasteners designed to prevent nuts, bolts, and screws from loosening under vibration, shock, or torque. Unlike flat washers, which simply distribute load, lock washers create resistance that keeps fasteners securely in place, ensuring long-lasting and reliable connections in various applications.

Features of Lock Washers

Anti-Loosening Design: Lock washers are engineered with shapes or serrations that provide friction and tension, reducing the risk of fastener loosening.

Variety of Types: Available in different designs such as split, toothed (inside and out), and conical to suit specific requirements.

Durability: Resistant to wear and tear, Lock washers ensure long-term performance under harsh conditions.

Corrosion Resistance: Lock washers are available with coatings like zinc plating, stainless steel finish, or phosphate treatment for enhanced protection.

Applications of Lock Washers

Lock washers are widely used across industries to maintain joint integrity where vibration or movement is a concern. Common applications include:

  • Automotive Industry: Securing engine components, transmissions, and suspension systems.

  • Aerospace & Aviation: Maintaining fastener stability in high-vibration environments.

  • Machinery & Equipment: Ensuring bolts stay tight in rotating or moving parts.

  • Electrical Assemblies: Providing secure fastening for electrical terminals and panels.

  • Construction & Structural Projects: Used in bridges, steel frameworks, and heavy machinery installations.
