S-98687A306 10.5 mm ID x 20 mm OD DIN 125; ISO 7089 General Purpose Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from black oxide steel construction for longer service life in demanding environments
• Precise dimensional accuracy with 10.5mm ID, 20mm OD and 2mm thickness ensuring perfect fit with M10 fasteners
• Superior load distribution across mating surfaces to prevent component damage and loosening
• Full compliance with international standards including DIN 125 and ISO 7089 for guaranteed interchangeability
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations for global supply chain compatibility
• Reliable performance in industrial assemblies due to consistent thickness and flatness characteristics
• Cost-effective protection for expensive components by absorbing vibration and preventing surface wear

Professional Applications & Engineering Value

These M10 metric flat washers provide essential engineering solutions where surface protection and load distribution are critical. The black oxide steel construction offers superior corrosion resistance compared to plain steel, making them ideal for automotive assemblies, machinery manufacturing, and outdoor equipment where moisture exposure is common. The precision flat washer design according to DIN 125 and ISO 7089 standards ensures perfect compatibility with M10 fasteners, eliminating installation issues and reducing assembly time. The consistent 2mm thickness provides reliable spacing and prevents over-compression of sensitive materials. These industrial washers effectively solve common engineering challenges by protecting finished surfaces from damage, distributing clamp load evenly, and preventing fastener loosening due to vibration - all while maintaining RoHS and REACH compliance for international projects.

Specification Summary & Compliance

Manufactured to exacting DIN 125 and ISO 7089 dimensional standards with 10.5mm internal diameter, 20mm outer diameter, and consistent 1.8-2.2mm thickness range. The black oxide steel construction provides enhanced surface protection. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance. Designed specifically for use with M10 screw sizes in metric fastening systems.
