The 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 SPC4 may be manufactured to many of the ASTM, ISO, SAE, or any specific customer standards — with various types of head configurations. Learn more here.
The SPC4 joint, available from Valley Forge & Bolt, 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 joint offers maximum joint integrity with optimum performance.
Additionally, the SPC4 Load Indicating System allows users to install a bolted assembly with confidence. The user is able to constantly monitor the clamp load of any SPC4 bolted joint, whether static or dynamic.
By easily attaching a probe to the datum disc located on the end of the fastener, the user is able to read the value on a hand held battery powered digital monitor.
Optional data gathering and storage of the bolted joint are also available. Wireless Load Monitoring and Data Logging with the SPC4 technology that’s designed to meet specific and tailored applications, is also available.
