TONSAN 1769 is a black anti-seize bolt lubricant that gives a uniform and lower torque coefficient K (0.108). It offers a low friction factor and stable torque coefficient, prevents clamping during assembly and reduces wear and corrosion; it has been used since 2014 on M16~64 high-strength bolts (wheel hub tooling bolts, blade-to-hub bolts). FEYANA supplies TONSAN 1769; contact us for packaging options.
