S-96025A373 4.3 mm ID x 8 mm OD Clipped Washers

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust and environmental degradation, extending service life in demanding industrial settings.
• Optimized for M4 Fastener Systems: Precision 4.3mm inner diameter ensures a perfect fit and secure seating on M4 screws, preventing loosening and improving assembly integrity.
• Superior Load Distribution: The 8mm outer diameter offers a wider bearing surface, effectively distributing pressure and protecting components from damage under heavy loads.
• Secure Anti-Rotation Design: The unique 7.1mm clipped width prevents the washer from spinning during installation and operation, ensuring consistent performance and easier assembly.
• Durable Mechanical Strength: With a Rockwell B40 hardness rating, this washer maintains its shape and function under significant stress and vibration.
• Consistent Performance: Tight thickness tolerance (0.4-0.6mm) guarantees uniform performance and reliable spacing in automated or high-volume assembly lines.
• Compliant for Global Markets: Meets RoHS 3 and REACH environmental standards, ensuring safe use and simplifying procurement for international industrial projects.

Professional Applications & Engineering Value

Engineered for precision and endurance, this M4 clipped washer tackles common industrial challenges like component wear, fastener loosening, and corrosion. The zinc-plated steel material offers a robust barrier against moisture and chemicals, making it ideal for automotive assemblies, machinery, and outdoor equipment where exposure is a concern. The clipped design is a key feature for applications requiring anti-rotation security, such as in conveyor systems or electrical enclosures, where a standard round washer might slip. Its metric dimensions and specific compatibility with M4 screw sizes ensure seamless integration into existing designs, reducing assembly time and improving the reliability of the final product. This washer delivers consistent engineering value by enhancing joint stability and protecting sensitive surfaces.
