ARP Fastener Assembly Lube - It's difficult to determine the correct pre-load and clamp force of a given fastener. For example- when tightened, dry uncoated fasteners use up about 95% of the torque applied to them overcoming the friction between the male and female threads. To ensure that all ARP fasteners provide the optimal level of service, the installed residual stress is calculated and verified expirimentally using a superior quality lubricant. It is important to note that the friction coefficients of lubricants vary dramatically, making it difficult to produce the exact amount of stress within the fastener to clamp the components together. That's why ARP developed an ultra consistent lubricant and reccomend the use of our premium grade assembly lubricant or thread sealer in order to precisely duplicate the reccomended tightening specifications provided with all ARp fasteners. Assembly lube specifications: Premium grade moly base with rust and corrosion inhibitors. Effective lubrication range: -30 degrees F to 750 degrees F. Load range: 500,000 psi. Other applications: primary assembly lube for engine components, press fitting,gear trains, and general machinery. Thread sealer specifications: PTFE based with rust and corrosion inhibitors. Effective range: .30 degrees F to 550 degrees F. Sealant range: 10,000 psi. Applications: delivers a flexible leak proof seal in aluminum, stee, stainless steel, and plastic against coolants, water, gasoline, natural gas and lpg. Designed for use with bolts
