Rapidstick 8243-250 Threadlocker

Rapidstick 8243 Threadlocker is fast curing with medium strength for bonding and sealing threads of less active material, such as stainless steel and plated parts. It is ideal for fasteners with diameters between 6mm to 20mm (1/4″ to 3/4″), and is highly resistant to heat, vibrations, water, gases, oils, hydrocarbons, and many chemicals.

8243 locks and seals threaded joints, nuts, screws, and studs with improved oil resistance, and is specifically formulated to give controlled friction and torque/tension ratio during assembly. It performs best in thin bond gaps, and can also be used for the retaining of cylindrical parts.

8243 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.
