Loctite™ Thread Lock

From extensive testing with Loctite™ and similar products we have established the following common sense rules for useage that need to be followed for effective outcomes when using these locking compounds:

The common characteristics of these materials is that they will harden when there is an absence of oxygen AND the presence of a metal which includes stainless steel.

  • Both male and female threads must be clean and dry
  • Locking fluid must be applied to ensure both threads are fully covered
  • The presence of the material is more important than the grade
  • Both medium strength blue and high strength red are very effective
  • These compounds will set underwater inside 24 hours
  • To mount underwater you should use the newer Loctite™ Stick grade

When utilised under the above conditions these types of material  will provide very secure locking over long periods of time.Our testing covers the following products
