Professional Applications & Engineering Value
This Acetal Plastic Spring Lock Washer is engineered to solve critical challenges in demanding applications. Its Acetal material offers inherent corrosion resistance, eliminating the risk of galvanic corrosion when used with dissimilar metals and making it perfect for chemical processing, marine, and outdoor equipment. The spring lock design delivers consistent anti-vibration performance, securing No. 10 and M5 screws in assemblies subject to dynamic loads or thermal cycling. As a non-conductive component, it provides essential electrical insulation in control panels, electronic enclosures, and automotive systems. Its ability to perform across a broad temperature range from -40°F to 212°F ensures reliability in everything from freezer units to machinery operating at elevated temperatures, offering a durable, maintenance-free fastening solution.
Specification Summary & Compliance
This washer features precise dimensions with an ID of 0.235", OD of 0.416", and a thickness of 0.030-0.040". It is compliant with RoHS 3 (2015/863/EU) and is suitable for use in both inch and metric systems. The material hardness is specified as Rockwell M80, ensuring dimensional stability and performance under load.
