Description
The 304 Stainless Steel GB862.2 External Tooth Lock Washer is a high-performance locking fastener designed to prevent loosening of bolts and nuts in vibration-prone applications. Manufactured according to the GB862.2 standard, this External Tooth Lock Washer features serrated external teeth that bite into the contact surface to enhance friction, providing a secure, anti-slip locking effect for reliable fastening. Its 304 stainless steel construction ensures strong corrosion resistance, durability, and long-term performance. This outer tooth lock washer offers strong anti-slip and anti-loosening performance, superior corrosion resistance, and long-term fastening stability—making it an ideal choice for reliable mechanical fastening in vibration-intensive applications.
Features & Benefits
