- Secure anti-rotation performance thanks to the 23.3mm clipped design, ensuring stable positioning under vibration and dynamic loads
- Precision M8 screw compatibility with 9mm inner diameter, providing accurate fit and reducing assembly time
- Consistent mechanical strength from Rockwell B55 hardness, maintaining structural integrity under repeated stress
- Regulatory compliance assurance with RoHS 3 and REACH standards, meeting global environmental and safety requirements
- Optimized thickness range (1.4-1.8mm) for balanced flexibility and rigidity in various mounting applications
Professional Applications & Engineering Value
Engineered for industrial machinery, automotive assemblies, and electrical enclosures, this M8 clipped washer addresses critical challenges in vibration-prone environments. The black-oxide steel construction provides a protective barrier against oxidation and mild chemical exposure, significantly reducing maintenance frequency. Its clipped width of 23.3mm prevents rotational slippage during torque application, ensuring reliable fastening in high-cycle production lines. With metric dimensions tailored for M8 screws, it delivers precise alignment in automated assembly systems while the Rockwell B55 hardness maintains dimensional stability under constant mechanical stress, making it ideal for heavy-duty equipment and structural frameworks.
Specification Summary & Compliance
This washer meets standard metric dimensional tolerances with ID 9mm, OD 28mm, and thickness 1.4-1.8mm. Manufactured from black-oxide steel with Rockwell B55 hardness, it ensures consistent performance in industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms adherence to environmental and safety standards for global supply chain integration.
