S-91455A330 3.2 mm ID x 7 mm OD DIN 125; ISO 7089 General Purpose Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc plating, extending service life in humid or demanding industrial environments.
• Reliable load distribution with a precise 7mm OD and 3.2mm ID, preventing surface damage and loosening under M3 screw assemblies.
• Consistent performance ensured by Rockwell B91 hardness, providing excellent durability and resistance to deformation.
• Guaranteed interchangeability by conforming to DIN 125 and ISO 7089 standards, ensuring perfect fit in global metric applications.
• Secure environmental compliance with RoHS 3 and REACH, making them safe for use in regulated industries and international supply chains.
• Optimal thickness control (0.4-0.6mm) for precise spacing and vibration damping without adding unnecessary bulk.

Professional Applications & Engineering Value

This M3 flat washer is engineered from zinc plated steel to address common industrial challenges like corrosion-induced failure and assembly inconsistency. Its metric dimensions and adherence to DIN 125 and ISO 7089 ensure reliable performance in machinery, automotive, and electronics assembly, where precise thread protection and surface preservation are critical. The zinc coating provides a sacrificial layer, significantly reducing rust and wear, while the controlled hardness prevents flattening under torque. This makes it an ideal choice for B2B procurement seeking cost-effective, long-lasting industrial washers that meet rigorous international standards.

Specification Summary & Compliance
