Important excerpt from the ARP catalog regarding proper fastener installation: “The importance of tightening fasteners to their required preload cannot be emphasized enough. If a fastener is not preload cannot be emphasized enough. If a fastener is not tightened properly, the fastener will not apply the required preload on the application it is being used for and may become susceptible to failure. Conversely, if a fastener is over tightened and stretched too much, it becomes susceptible to failure by exceeding it’s maximum yield point.”
