How to Apply Loctite Sticks

Threadlocking and Anti-Seize

  • For best results, clean all surfaces (external and internal) with a Loctite cleaning solvent and allow to dry.
  • Advance enough stick product to use at the time of application.  Typically less than 1/8”.  A good rule of thumb is to advance the stick only as deep as the threads you are applying to.
  • Apply sufficient product to fill the threads in the area where the nut will be engaged on the bolt.
  • Assemble and tighten as required.
  • Recap product after use.

Thread Sealing

  • For best results, clean all surfaces (external and internal) with a Loctite cleaning solvent and allow to dry.
  • Advance enough stick product to use at the time of application.  Typically less than 1/8”.  A good rule of thumb is to advance the stick only as deep as the threads you are applying to.
  • Apply sufficient product to fill all the engaged threads.
  • Use accepted trade practices to assemble and tighten fittings until proper alignment is obtained.
  • Recap product after use.
  • This product performs best in thin bond gaps.  Very large thread sizes may create large gaps, which will affect cure speed and strength.
  • For maximum pressure and solvent resistance, allow at least 24 hours for product to fully cure before filling and pressurizing the system.

Retaining

  • For best results, clean all surfaces (external and internal) with a Loctite cleaning solvent and allow to dry.
  • Advance only enough product to use at the time of application.

For Slip Fitted Assemblies

  • For applications with a diameter less than approximately 40 mm, apply product to the pin (inner component) around the entire circumference of the surface being bonded (e.g. pin exterior). Product should be applied at the point where the bonded components will ultimately be positioned. For best results, rotate either part during assembly to ensure full coverage of the product in the engagement area.
  • For applications with a diameter greater than approximately 40 mm, it is recommended to apply stick product around the entire circumference of both surfaces being bonded (e.g. pin and collar). Product should be applied at the point where the bonded components will ultimately be positioned. For best results, rotate either part during assembly to ensure full coverage of the product in the engagement area.

For Press Fitted Assemblies

  • Apply product thoroughly to both bond surfaces and assemble at high press rates to avoid premature curing during assembly.

For Shrink Fitted Assemblies

  • Apply product around the entire circumference of the innermost surface being bonded (i.e. pin). Product should be applied at the point where the bonded components will ultimately be mated. Heat collar to achieve sufficient clearance for free assembly of the parts.  Position parts and allow to cool.
  • Parts should not be disturbed until sufficient handling strength is achieved.

Flange Sealing

  • For best results, clean all bond surfaces with a Loctite cleaner degreaser and allow to dry.
  • Advance only enough stick product to use at the time of application. Typically 3mm.
  • Apply manually by wiping the advanced stick directly on one surface of the flanges.
  • Flanges should be mated and tightened as soon as possible after assembly to avoid shimming.

Gasket Dressing

  • For best results, clean all bond surfaces with a Loctite cleaner degreaser and allow to dry.
  • The product is designed for use in conjunction with precut gaskets as a gasket tacking/dressing agent.
  • Advance only enough stick product to use at the time of application. Typically 3mm.
  • Apply manually by wiping the advanced stick directly on the surface of the flange.
  • Position the gasket on the tacky surface of the applied material to hold it in position.
  • Flanges should be mated and tightened as soon as possible after assembly to avoid shimming.
