Rapidstick 8242 Threadlocker

Rapidstick 8242 Threadlocker is fast curing with medium strength and specifically formulated to give controlled friction and torque/tension ratio during assembly. It is designed for plated parts and vibrating or moving components, and is ideal for fasteners with diameters between 6mm to 20mm (1/4” to 3/4″).

8242 provides a chemically resistant lock and seal to threaded joints, nuts, screws, and studs, meeting 90% of all nut and bold thread locking applications, and performs best in thin bond gaps. It can also be used for the retaining of cylindrical parts

8242 meets Military Specifications:

  • MIL-S-46163 Type II, Grade N
  • MIL-S-22473E Letter Grade CVV

Chemtools® Rapidstick range of Threadlockers have been designed to offer controlled friction and torque/tension for sealing and locking varying sizes of studs, nuts, screws, bolts, joints, and fittings. Our Threadlockers provide the highest level of shock and vibration resistance – whether on moving components, or solid, heavy duty assemblies – and prevent loosening and the leakage of chemicals, water, gases, and oils.


From hairline cracks and porous surfaces, through to construction equipment and high temperature environments, Rapidstick Threadlockers, with slow or fast cure fixture times, low to high strengths, and permanent or removable formulas, are all guaranteed for bond stability and high performance – as well as peace-of-mind maintenance and repair..
