Products Detail
EN 14399-6 is a critical European standard that specifies hardened plain chamfered washers for high-strength preloaded structural bolting systems. As an essential supporting component for EU-standard steel structure fastening assemblies, EN 14399-6 chamfered washers are specially manufactured for matching preload structural bolt and nut sets. Featuring precision chamfered edge design and integral quenched & tempered hardening treatment, these washers effectively distribute fastening preload evenly, prevent surface pressure concentration, avoid connection slippage and structural indentation, and greatly improve the overall stability and fatigue resistance of structural connections under long-term dynamic loads, vibration and temperature fluctuations.
Our EN 14399-6 chamfered washers are produced with precision stamping and fine finishing technology, featuring flat and smooth surface, uniform thickness and precise chamfer dimension. All products undergo professional standardized heat treatment to achieve stable hardness performance and excellent structural toughness. Strictly manufactured in accordance with EU industrial specifications, these hardened washers deliver outstanding pressure resistance, wear resistance and deformation resistance. The standardized chamfer structure ensures perfect fitting with high-strength structural bolt assemblies, avoiding assembly interference and guaranteeing accurate preload transmission and consistent connection performance.
EN 14399-6 hardened chamfered washers are widely used in high-standard steel structure engineering, high-rise building construction, bridge infrastructure, industrial plant frame installation and large municipal structural projects. They are indispensable matching fasteners for EU preloaded high-strength structural connection systems, effectively protecting connected substrates, stabilizing bolt preload and ensuring long-term structural safety and reliability of engineering facilities.
