Internal Tooth Lock Washers Black Zinc

Internal Tooth Lock Washers Black Zinc. The combination of surface treatment and material provides additional advantages.

（1）Outstanding corrosion resistance

The salt spray resistance time of the black zinc coating is typically 72-120 hours, which is several times longer than that of ordinary blackening treatment. Therefore, the Internal Tooth Lock Washers Black Zinc can withstand more demanding humid or mild corrosive environments.

（2）Excellent aesthetics and recognizability

It has a uniform black matte appearance, which not only meets the aesthetic requirements of the equipment, but also serves as a visual identifier on the assembly line, facilitating operators to quickly identify and classify.

（3）Outstanding vibration and impact resistance

After being engaged, the toothed insert can maintain the preload of the fastener in a high-intensity vibration environment, preventing loosening caused by long-term vibration or impact loads.

（4）Reliable electrical grounding performance

It can destroy the non-conductive coating on the contact surface through mechanical means, forming a low-resistance stable conductive connection, ensuring the long-term effectiveness of the electrical equipment grounding system.

（5）Standardization of raw materials and specifications

Mainly made of high-strength spring steel, offering a full range of sizes in both metric and imperial standards.

Core application fields

The Internal Tooth Lock Washers Black Zinc is a choice that combines high corrosion resistance with professional aesthetic appearance. It is an ideal core component in multiple industrial fields with strict requirements for performance and the environment.

（1）Automobile manufacturing

It is commonly used for fastening and anti-loosening in key parts such as engines, gearboxes, and braking systems. It can effectively cope with continuous vibrations during vehicle operation and salt and mud erosion.

（2）Industrial machinery

Suitable for various machine tools, conveying equipment and heavy industrial equipment, it can ensure the long-term stability of the connection during continuous operation and high load, reducing downtime and maintenance due to vibration.
