Professional Applications & Engineering Value
Engineered for high-stress mechanical assemblies, these M14 flat washers provide critical load distribution where Class 10.9 fasteners are employed. The zinc-plated steel construction offers superior corrosion protection in manufacturing plants, automotive applications, and structural steel connections. With precise DIN 9021 specifications, these metric washers prevent fastener embedding in soft materials and distribute clamping forces across wider surfaces. The controlled thickness tolerance (2.7-3.3mm) ensures consistent performance in heavy-duty applications subject to vibration and dynamic loading, making them ideal for machinery bases, engine components, and structural frameworks where joint integrity is paramount.
Specification Summary & Compliance
This flat washer meets DIN 9021 dimensional standards with 15.1mm internal diameter, 43.6mm outer diameter, and 2.7-3.3mm thickness range. Manufactured from zinc-plated steel specifically for use with M14 Class 10.9 fasteners. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe usage across industrial sectors.
