S-91455A612 8.4 mm ID x 16 mm OD DIN 125; ISO 7089 General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in harsh environments
• Precise dimensional fit with 8.4mm ID for reliable M8 screw seating and 16mm OD for optimal load distribution
• Enhanced durability from Rockwell C30 hardness, resisting deformation under heavy loads
• International compliance with DIN 125 and ISO 7089 standards, ensuring interchangeability and quality
• Environmental safety through RoHS 3 and REACH compliance, meeting global regulatory requirements
• Consistent thickness (1.4-1.8mm) for uniform pressure application and joint stability
• Cost-effective protection for equipment by preventing loosening and surface damage

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M8 flat washers in zinc plated steel provide critical solutions for vibration management and corrosion prevention. The metric dimensions and adherence to DIN 125 and ISO 7089 standards ensure seamless integration in machinery assembly, automotive systems, and structural frameworks. By distributing clamp load evenly, they mitigate stress concentration on surfaces, reducing wear and maintenance costs. The Rockwell C30 hardness guarantees structural integrity under cyclic loading, while the zinc coating offers a sacrificial layer against moisture and chemicals, making them ideal for outdoor or high-humidity applications where fastener failure is not an option.

Specification Summary & Compliance

This flat washer conforms to dimensional tolerances per DIN 125 and ISO 7089 standards, with inner diameter of 8.4mm, outer diameter of 16mm, and thickness range of 1.4-1.8mm. Manufactured from zinc plated steel with a hardness of Rockwell C30, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for hazardous substance restrictions, ensuring safe use across global industrial supply chains.
