S-98691A216 6.4 mm ID x 12 mm OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from nickel plating over brass, ideal for humid or chemically exposed environments
• Precise dimensional fit with 6.4mm ID and 12mm OD ensuring reliable seating and load distribution for M6 screws
• Durable brass core providing excellent electrical conductivity and non-magnetic properties for specialized assemblies
• Consistent thickness range (1.4-1.8mm) for uniform pressure distribution and vibration resistance
• Full regulatory compliance with RoHS 3 and REACH standards, meeting international environmental and safety requirements
• Long-term reliability in demanding applications due to material integrity and corrosion-resistant plating

Professional Applications & Engineering Value

Engineered for precision assemblies requiring corrosion resistance and electrical conductivity, these nickel plated brass flat washers solve critical challenges in electronics, marine, and chemical processing equipment. The M6 metric flat washer design ensures perfect compatibility with standard fasteners while the brass material with nickel plating prevents galvanic corrosion when used with dissimilar metals. This combination delivers exceptional performance in electrical grounding applications, plumbing systems, and precision instrumentation where both environmental durability and reliable electrical properties are essential. The precise 6.4mm inner diameter prevents screw movement while the 12mm outer diameter optimally distributes clamping force.
