Professional Applications & Engineering Value

This M12 metric flat washer delivers exceptional engineering value in demanding applications where thermal stability and electrical insulation are critical. The fiberglass construction provides outstanding resistance to heat up to 280°F, making it ideal for automotive, electrical enclosures, and industrial machinery components exposed to elevated temperatures. Its precise 13mm ID and 20mm OD dimensions ensure perfect compatibility with M12 screws, preventing loosening and maintaining consistent clamping force. The material's inherent non-conductive properties eliminate electrical conductivity risks in sensitive electronic assemblies, while the Rockwell M115 hardness guarantees dimensional stability under vibration and load. These characteristics solve common industrial pain points including thermal expansion mismatches, electrical isolation requirements, and maintenance frequency reduction in high-stress environments.

Specification Summary & Compliance

This flat washer features metric dimensions with 13mm internal diameter, 20mm outer diameter, and 1.4-1.8mm thickness range, engineered for M12 screw applications. Manufactured from fiberglass material with Rockwell M115 hardness rating, it maintains dimensional integrity across its operational temperature range. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components. This ensures restriction-free use in global markets while providing verification of material safety and environmental responsibility.
