Professional Applications & Engineering Value

These fiberglass flat washers deliver critical engineering solutions where thermal management and electrical insulation are paramount. The fiberglass material provides excellent dielectric properties while maintaining structural integrity under continuous exposure to temperatures reaching 280°F. This makes them ideal for industrial applications in electronics, automotive, and aerospace sectors where metric washers must prevent galvanic corrosion between dissimilar metals. The precise 2.7x5mm dimensions ensure proper load distribution for M2.5 fasteners, reducing stress concentration and preventing joint failure in vibration-prone environments. Their light green color facilitates quality control during assembly, while the Rockwell M115 hardness guarantees consistent performance through repeated thermal cycles.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 2.7 mm inner diameter and 5 mm outer diameter, these flat washers feature a thickness range of 0.3-0.5 mm for M2.5 screw applications. The fiberglass construction achieves Rockwell M115 hardness rating and maintains functionality up to 280°F maximum temperature. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for international industrial markets.
