Internal Tooth Lock Washer (DIN 6797J / GB 861.1)

Internal tooth lock washers are designed with teeth pointing inward, providing excellent locking performance by gripping the surface of the fastener or component. They are ideal for applications requiring resistance to vibration or loosening under dynamic loads.

Features and Performance:

• Material Options:

• Carbon Steel (65Mn, C75S): Provides high strength and elasticity.

• Stainless Steel (AISI 304, 316): Ensures corrosion resistance for use in harsh or outdoor environments.

• Phosphor Bronze or Brass: Available for electrical conductivity or decorative applications.

• Surface Treatment:

• Black oxide, zinc plating, or galvanized coating for enhanced corrosion protection.

• Passivation for stainless steel to improve surface durability.

• Performance:

• The inward-facing teeth dig into the mating surface, ensuring a secure hold.

• Effective in preventing loosening caused by vibration or thermal expansion.

Applications:

• Commonly used in electrical equipment, automotive assemblies, and machinery to enhance the locking effect of fasteners.

• Ideal for use in joints where the bolt or screw head needs extra grip and stability.
