Professional Applications & Engineering Value

This fiberglass flat washer is engineered to address common challenges in high-temperature and corrosive industrial applications, such as electrical enclosures, automotive systems, and machinery exposed to heat and chemicals. The fiberglass material provides excellent electrical insulation and chemical resistance, preventing failures caused by thermal expansion or exposure to harsh substances. With a Rockwell M100 hardness and precise inch-system dimensions (e.g., 0.312" ID for 5/16" screws), it ensures a tight, reliable fit that distributes load evenly, reducing stress on fastened components. Ideal for industrial washers in demanding settings, this product enhances safety and longevity by maintaining performance under extreme conditions, from high-temperature operations to environments requiring RoHS 3 and REACH compliance.

Specification Summary & Compliance

This washer adheres to inch-system standards with an inner diameter of 0.312", outer diameter of 0.562", and thickness range of 0.054-0.070", specifically designed for 5/16" screw sizes. It meets industry requirements for hardness (Rockwell M100) and maximum temperature (280°F), and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
