ARP MOLY ASSEMBLY LUBE – 1.69 OZ – 100-9903
It’s difficult to determine the amount of torque required to provide the correct preload and clamp force of a given fastener. For example – when tightened; dry uncoated fasteners use up about 95% of the applied torque simply by overcoming the friction between the male and female threads. To ensure that all ARP fasteners provide the optimum level of service; the installed residual stress is calculated and verified experimentally using a superior quality lubricant. It is important to note that the friction coefficients of lubricants vary dramatically; making it difficult to consistently produce the exact amount of stress within the fastener to clamp the components together. That’s why ARP developed an ultra-consistent lubricant and recommend the use of our premium grade ASSEMBLY LUBRICANT in order to precisely duplicate the recommended tightening specifications provided with all ARP fasteners.
