The GB93 2205/2507/310S/321 Stainless Steel Spring Lock Washer is a precision-engineered mechanical fastener component designed to prevent loosening of bolts and nuts caused by vibration, torque, or thermal expansion. Manufactured to GB93 standards, it offers consistent quality, dimensional accuracy, and high locking performance across a variety of demanding environments. Constructed from high-performance stainless steels such as 2205 duplex, 2507 super duplex, 310S heat-resistant, and 321 stabilized stainless steel, this spring washer provides exceptional mechanical strength, stress corrosion resistance, and durability under extreme conditions. It is ideal for industrial, marine, and high-temperature applications where long-term stability and safety are crucial.
