LOCTITE® 222 is a low-strength threadlocker that allows the adjustment of screws including countersunk head screws and set screws. Good on low-strength metals which could fracture during disassembly, e.g. aluminum or brass. The product works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces. t is proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids.
  • Ideal for low-strength threadlocking of adjusting screws, countersunk head screws and set screws
  • Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
  • Permits disassembly with hand tools
  • Especially suited to small thread sizes
  • P1 NSF Reg. No.: 123002
LOCTITE®222 is designed for the locking and sealing of
threaded fasteners which require easy disassembly with
standard hand tools. The product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration.
Particularly suitable for applications such as adjustment of
set screws, small diameter or long engagement length
fasteners, where easy disassembly is required without
shearing the screw. The thixotropic nature of LOCTITE®222
reduces the migration of liquid product after application to the

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The graph
below shows the breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials and
tested according to ISO 10964.
Cure Speed vs. Bond Gap

The rate of cure will depend on the bondline gap. Gaps in
threaded fasteners depends on thread type, quality and size.
The following graph shows shear strength developed with time
on steel pins and collars at different controlled gaps and tested
according to ISO 10123.
Cure Speed vs. Temperature

The rate of cure will depend on the temperature. The graph
below shows the breakaway strength developed with time at
different temperatures on M10 steel nuts and bolts and tested
according to ISO 10964.
Cure Speed vs. Activator

Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™ and 7649™ and tested according
to ISO 10964.

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
Directions for use:

For Assembly

  1. 1. For best results, clean all surfaces (external and internal)
    with a LOCTITE® cleaning solvent and allow to dry.
  2. If the material is an inactive metal or the cure speed is too
    slow, spray all threads with and allow to dry.
  3. Shake the product thoroughly before use.
  4. To prevent the product from clogging in the nozzle, do not
    allow the tip to touch metal surfaces during application.
  5. For Thru Holes, apply several drops of the product onto
    the bolt at the nut engagement area.
  6. For Blind Holes, apply several drops of the product down
    the internal threads to the bottom of the hole.
  7. Assemble and tighten as required.
  8. For Sealing Applications, apply a 360° bead of product
    to the leading threads of the male fitting, leaving the first
    thread free. Force the material into the threads to
    thouroughly fill the voids. For bigger threads and voids,
    adjust product amount accordingly and apply a 360° bead
    of product on the female threads also.

For Disassembly

  1. 1. Remove with standard hand tools.
  2. In rare instances where hand tools do not work because
    of excessive engagement length, apply localized heat to
    nut or bolt to approximately 250 °C. Disassemble while

For Cleanup

  1. Cured product can be removed with a combination of
    soaking in a Loctite solvent and mechanical abrasion
    such as a wire brush
