Professional Applications & Engineering Value
This M16 flat washer in zinc plated steel delivers critical engineering solutions by addressing common industrial challenges like fastener loosening, surface abrasion, and corrosion. Its metric dimensions (17mm ID, 30mm OD) and controlled thickness ensure uniform load distribution, preventing joint failure in heavy-duty applications such as structural steelwork, machinery frames, and automotive components. The zinc coating acts as a sacrificial layer, combating rust in humid or outdoor settings, while adherence to DIN 125 and ISO 7089 standards ensures precise threading compatibility and reduces assembly errors. Engineers value its Rockwell B75 hardness for maintaining integrity under vibration, making it a reliable choice for industrial washers in demanding environments.
Specification Summary & Compliance
This flat washer features a 17mm inner diameter, 30mm outer diameter, and 2.7-3.3mm thickness with Class A dimensional tolerances per DIN 125 and ISO 7089 standards. It is manufactured from zinc plated steel with a Rockwell B75 hardness for consistent mechanical properties. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use worldwide.
