Description
TORQUE SEAL WHITE -20ML — BOLTON SKU 65564.
About the MPN: LB-11000 torque seal lacquer
This item is a torque seal — a tamper-evident inspection lacquer supplied in a 20 ml unit in white. Torque seal is applied as a small stripe across the interface between a torqued fastener and its mating surface (for example across a nut, bolt head and adjacent structure) after final torquing. Once dry, the brittle lacquer stripe cracks or breaks away if the fastener subsequently rotates, giving inspectors an immediate visual indication of loosening or tampering without re-checking torque on every fastener. This practice is standard in aircraft and UAV maintenance, where torque-striping of critical joints is part of routine build and inspection discipline. White is one of several standard colours used to distinguish inspection stages or teams. Chemical composition, drying time and surface compatibility for this specific product should be confirmed against the supplier’s technical data sheet at order stage.
