Features:

1. Anti-Loosening Function: The primary feature of an internal tooth washer is its ability to prevent nuts and bolts from loosening due to vibrations or external forces. The teeth grip into the mating surface, offering more friction.

2. Enhanced Grip: Provides a better grip on softer materials like aluminum or plastic, which may otherwise allow a standard washer or nut to loosen over time.

3. Corrosion Resistance: Typically coated or made from stainless steel, offering resistance to rust and corrosion in different environments, such as marine or high-humidity conditions.

4. Cost-Effective: Offers a low-cost solution for improving the reliability and security of mechanical assemblies, reducing the need for more expensive or complex locking mechanisms.

5. Easy Installation: Simple to install and require no additional tools beyond a standard wrench or screwdriver to be effective.

6. Durability: Designed for high durability, internal tooth washers have a longer lifespan compared to standard flat washers due to their unique construction.

Uses of Internal Tooth Washer:

• Automotive Applications: Used in vehicles to secure fasteners in places where vibration is frequent (e.g., engine parts, suspension components).
• Industrial Equipment: Ideal for use in machinery, heavy-duty equipment, and construction tools that experience high levels of movement or force.
• Electrical Industry: Commonly used in electrical panels or equipment to prevent loosening of terminals or connectors.
• Aerospace: In applications where vibration resistance is critical, internal tooth washers are commonly used in aircraft assembly.
• Home Appliances: Found in various household appliances, where bolts and screws may loosen over time due to frequent usage.
• HVAC Systems: Used to ensure that critical parts of heating, ventilation, and air conditioning systems remain secure despite external vibrations.
