The solution to bolt preload problems!


The bolt preload provides a clamp force that prevents gaps from occurring at the joint faces, or lateral movement, when external forces are applied. It provides the loading that generates the frictional force between the joint faces to prevent slippage and the load to ensure that any gasket within the joint, seals effectively. If the bolt preload is not sufficient to resist the external forces, loosening, fatigue or wear problems can be anticipated. BOLTCALC will establish if such a condition is likely to arise.
