Professional Applications & Engineering Value
These nickel-plated brass countersunk washers deliver critical engineering solutions where corrosion resistance and aesthetic finish matter. The 90° countersink angle ensures perfect flush mounting in precision applications like electronic enclosures, marine hardware, and architectural fixtures where protruding fasteners are unacceptable. The brass core provides excellent conductivity while the nickel plating creates a durable barrier against moisture, chemicals, and galvanic corrosion. Ideal for M5 screw applications in manufacturing, automotive, and electrical industries, these metric washers prevent loosening from vibration and distribute clamp load effectively across delicate surfaces.
Specification Summary & Compliance
Manufactured to DIN standard specifications with precise metric dimensions: 7mm ID, 15mm OD, and 2.5mm overall height. Features a standardized 90° countersink angle for universal compatibility with countersunk screw heads. Fully compliant with RoHS 3 (2015/863/EU) environmental directives, ensuring safe use in electronic and consumer product applications. The nickel-plated brass construction provides consistent dimensional accuracy for reliable performance in metric fastening systems.
