Professional Applications & Engineering Value
These M8 countersunk washers solve critical engineering challenges in applications requiring flush surface mounting while maintaining corrosion resistance. The 90° countersink angle precisely matches standard countersunk screw heads, preventing surface protrusions that could compromise safety or aesthetics in machinery, automotive, and electronic enclosures. Manufactured from aluminum, these metric washers offer an optimal strength-to-weight ratio, making them ideal for weight-sensitive applications in aerospace and transportation industries. The DIN 6797 standard ensures dimensional accuracy and reliable performance in high-vibration environments, while the material's natural oxide layer provides built-in protection against environmental degradation without additional coatings.
Specification Summary & Compliance
This countersunk washer features precision metric dimensions with 8.4mm inner diameter and 25mm outer diameter, designed specifically for M8 fastener systems. The component maintains standard DIN 6797 specifications with 90° countersink angle and 4.8mm overall height. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international substance restriction standards for industrial components.
