• Excellent load distribution due to the large 3" OD and 0.235-0.265" thickness, minimizing surface pressure and preventing material damage
• Precise fit for 1/2" screws with a 0.562" ID, ensuring secure fastening and reducing assembly errors
• Enhanced durability from Rockwell B40 hardness, providing reliable performance under repeated stress
• Compliance with RoHS 3 and REACH regulations, meeting strict environmental and safety standards for global industrial use
• Heavy-duty construction in inch system, offering robust support for demanding applications
• Long-term reliability in corrosive conditions, reducing maintenance needs and replacement costs

Professional Applications & Engineering Value

This hot-dipped galvanized steel flat washer is engineered to address common industrial challenges such as corrosion and uneven load distribution. The galvanized coating provides a robust barrier against moisture and chemicals, making it ideal for outdoor machinery, construction projects, and marine equipment where corrosion resistance is critical. With a 3" outer diameter and substantial thickness, it effectively spreads load over a wider area, preventing bolt loosening and surface indentation in heavy-duty assemblies like structural steel connections and automotive frames. By ensuring consistent performance in demanding environments, this washer reduces downtime and enhances the longevity of industrial fastening systems, supporting efficient B2B procurement for reliable, compliant components.

Specification Summary & Compliance

This flat washer adheres to inch system measurements with an ID of 0.562", OD of 3", and thickness range of 0.235-0.265" for precise fit with 1/2" screws. It meets RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead in steel and is REACH (EC 1907/2006) compliant as of 01/17/2023, ensuring environmental and safety standards are upheld in industrial applications.
