Wide range of structural bolting assemblies for preloading, according to the standards EN 14399 used for structural applications.

Currently there is a very clear European legislation to define the basic characteristics of high strength structural bolting assemblies for preloading. Preload bolting assemblies must comply with EN 14399, which provide specific requirements regarding manufacture, materials and testing.

The UNIVITI structural bolting includes high strength friction grip bolts and associated nuts and washers (HV system) for structural engineering. Preloaded bolted assemblies are very sensitive to differences in manufacture and lubrication. Therefore it is important that the assembly is supplied by one manufacturer. Beside the mechanical properties of the components, the functionality of the assembly requires that the specified preload can be achieved if the assembly is tightened with a suitable procedure.

Contact us for further information regarding structural bolting according to EN 14399 and all the other elements listed in our catalogue.
