Standard:EN14399-6
Description:
EN 14399-6 chamfered washers are specialized washers that conform to the European standard EN 14399-6, which specifies the requirements for washers used with high-strength structural bolts. These washers are designed with chamfered edges to provide a smooth transition and reduce the risk of stress concentrations, enhancing the durability and performance of bolted connections.
The EN 14399-6 washer is made from hardened steel, which provides increased strength and durability. It is available in various sizes ranging from M12 to M36, with the "M" indicating the metric thread size and the number representing the nominal diameter of the fastener it is designed to be used with.
