Professional Applications & Engineering Value

These UHMW plastic flat washers are engineered to address common industrial challenges, such as chemical exposure and mechanical stress. Made from ultra-high-molecular-weight polyethylene, they provide outstanding chemical resistance, preventing deterioration in environments with oils, acids, and alkalis. The metric dimensions (19mm ID x 34mm OD) and compatibility with M18 screws ensure precise alignment and secure fastening in machinery, conveyor systems, and automotive assemblies. Their off-white color allows for easy identification, while the temperature range up to 180°F supports use in both indoor and moderate outdoor settings. Ideal for applications in food processing, material handling, and electrical enclosures, these washers reduce maintenance needs and enhance operational reliability by resisting abrasion and minimizing galvanic corrosion.
