This gauge has been developed to provide optimum accuracy in determining the correct pre-load in the installed rod bolt. The products main purpose is to obtain the proper torque load when installed in the engine, and monitoring the condition of the bolt while in use. This is particularly useful if an engine is internally monitored regularly.
