Contact SupplierThe integrity of a bolted joint is jeopardized when fasteners lose their tension. This loss of clamping force begins during assembly due to elastic interactions and joint relaxation. Self-loosening continues when the joint is put in service due to vibrations, shock, temperature changes, embedment, etc.
The SPC4â„¢ joint allows the end-user to re-tighten only the bolts or studs that have lost their clamp load. This results in a tremendous saving of maintenance time, money and replacement parts. For a minimal investment, the SPC4â„¢ offers maximum joint integrity with optimum performance.
