Loctite threadlocking products prevent self-loosening and secure any threaded fastener against vibration and shock loads. Completely filling the gap between mating threads, they permanently secure threaded assemblies and eliminate fretting corrosion. Browse their full range below.

Low strength threadlockers are typically applied to adjustment screws, calibration screws, meters, and gauges, which undergo frequent disassembly and can be removed using hand tools.
Medium strength threadlockers are suitable for machine tools, presses, pumps, compressors, mounting bolts, and gearboxes, where disassembly occurs with normal frequency and can be done using hand tools.
High strength threadlockers are employed in more permanent assemblies such as heavy equipment, suspension bolts, motor and pump mounts, cap bolts, and studs. These applications rarely require disassembly and may require localised heat for effective removal.
A threadlocker is a liquid adhesive designed to secure fasteners from loosening between maintenance cycles. At Loctite, the threadlocker has become widely known as the “red bottle” due to its distinctive look.
When fasteners loosen, this can cause serious accidents and a total shutdown of a production plant. Threadlockers add an extra level of protection by defending against improper tightening, shocks and vibration, thermal expansion and corrosion.
Unlike conventional fastening methods such as double nuts and spring washers, Loctite threadlockers maintain clamping force, fill all gaps and provide an air-tight seal.
