Professional Applications & Engineering Value
This M20 spring lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications where equipment reliability is paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance in chemical processing, marine, and outdoor environments, while the top and bottom serration design ensures maximum locking force by biting into both mating surfaces. Engineered with Rockwell C38 hardness, these metric lock washers maintain consistent spring tension under dynamic loads, preventing joint failure in machinery, automotive assemblies, and structural frameworks. The dual-serrated configuration solves common loosening issues in vibration-prone equipment, making them ideal for manufacturing plants, transportation systems, and heavy machinery where fastener integrity cannot be compromised.
Specification Summary & Compliance
This metric spring lock washer features precise dimensions with 0.827" internal diameter for M20 screw compatibility, 1.181" outer diameter, and 0.098" overall height. Manufactured from 18-8 stainless steel with Rockwell C38 hardness for consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial applications requiring regulated material compliance.
