Fastener Assembly Lubricants

Fastener assembly lubricants for controlled installation friction. Browse ARP Ultra-Torque and OptiTorque True Torq options, and select the exact lubricant specified in your fastener’s instructions. Torque values depend on the stated lubricant; do not assume different products are interchangeable. Thread sealers and general engine oils are excluded from this range.
