  • Superior load distribution with precise 26mm ID and 48mm OD dimensions, reducing stress on M24 fasteners
  • Exceptional durability from Rockwell C38 hardness, minimizing wear and deformation under heavy loads
  • Effective vibration resistance due to flat washer design, maintaining assembly integrity in dynamic applications
  • Compliance with global standards including RoHS 3 and REACH, ensuring safe and sustainable usage
  • Accurate metric sizing for seamless integration with M24 screws in international projects
  • Reliable thickness range of 3.4-4.6mm, providing consistent performance and easy installation

Professional Applications & Engineering Value

This M24 metric flat washer is engineered to address common industrial challenges such as joint loosening and material fatigue. The blue-dyed steel construction offers an added layer of corrosion protection, making it suitable for outdoor machinery, automotive assemblies, and construction equipment where exposure to moisture is a concern. Its Rockwell C38 hardness ensures the washer maintains shape under high clamping forces, preventing failure in heavy-duty applications. By evenly distributing load across a wider surface area (48mm OD), it reduces point stress on connected components, extending the lifespan of M24 fastener systems and minimizing maintenance downtime in vibrating environments like manufacturing plants and transportation infrastructure.

Specification Summary & Compliance

This flat washer adheres to metric system standards with an inner diameter of 26mm, outer diameter of 48mm, and thickness ranging from 3.4-4.6mm, designed specifically for M24 screw sizes. It meets Rockwell C38 hardness specifications for reliable mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use across various sectors.
