Description
The 304 Stainless Steel GB862.2 External Tooth Lock Washer is a high-performance locking fastener engineered to prevent the loosening of bolts and nuts in vibration-prone applications. Manufactured in strict accordance with the GB862.2 standard, this External Tooth Lock Washer features serrated external teeth specifically designed to bite into the contact surface. This mechanical action significantly enhances friction, providing a secure, anti-slip locking effect for reliable fastening. Constructed from premium 304 stainless steel, this Lock Washer ensures exceptional durability and long-term stability, making it a professional choice for mechanical assemblies facing intensive dynamic loads. It is suitable for use in industrial machinery, electrical assemblies, structural installations, and equipment exposed to movement or vibration.
Features & Benefits
- Superior Anti-Slip Teeth: The serrated external teeth provide maximum rotational resistance. They offer firm locking against backward slippage and dynamic loads to maintain joint integrity.
- 304 Stainless Steel Construction: This stainless steel washer guarantees excellent corrosion and oxidation resistance. It is perfectly suited for long-term performance in non-marine exterior environments.
- High Strength & Deformation Resistance: The material offers excellent hardness and wear resistance. Its high structural stability ensures that the washer maintains secure fastening over time without deforming under pressure.
- Improved Contact & Precision Fit: The thin profile is paired with a strong biting force to ensure a firm fit with bolts. This design provides a larger bearing surface, which further enhances the secure locking performance.

FAQ:
Q1: What is the primary advantage of the GB862.2 External Tooth Lock Washer?
A: The primary advantage is its serrated external teeth that bite into the contact surface to enhance friction. This provides maximum rotational resistance and prevents fasteners from backing out under vibration.
Q2: Is this stainless steel washer suitable for outdoor use?
A: Yes, the 304 stainless steel construction provides excellent corrosion and oxidation resistance. While it is ideal for non-marine exterior use, it ensures long-term durability in various humid or challenging environments.
Q3: How does the "biting force" assist in fastening?
A: The biting force created by the external teeth ensures a firm fit with the bolt head or nut. By increasing the mechanical grip on the mating surface, the washer effectively resists dynamic loads that would otherwise cause loosening.
Q4: Can this washer be used on larger bearing surfaces?
A: Absolutely. The design of the external tooth washer is intended to provide a larger bearing surface compared to internal versions, ensuring a more stable and secure lock for your fasteners.
