Professional Applications & Engineering Value

These M4 metric flat washers manufactured from hard fiber material provide critical solutions for industrial applications requiring both electrical isolation and mechanical protection. The black fiber construction delivers consistent performance as vibration-resistant washers in automotive assemblies, electrical enclosures, and machinery where metal-to-metal contact must be avoided. Engineers specify these DIN 125 compliant washers for their ability to prevent galvanic corrosion between dissimilar metals while maintaining dimensional stability under compression. The 0.7-0.9mm thickness range ensures proper sealing and load distribution without adding significant bulk to fastened joints, making them ideal for space-constrained applications requiring reliable electrical insulation washers.

Specification Summary & Compliance

This flat washer features precise metric dimensions with 4.3mm inner diameter, 9mm outer diameter, and 0.7-0.9mm thickness range, manufactured to DIN 125 standards for dimensional accuracy. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications. Maximum service temperature rating of 230°F (110°C) makes these washers appropriate for various industrial environments while maintaining their structural and insulating properties.
