Typical Applications

Threadlocking adhesive also known as thread locking fluid or threadlocker is a liquid resin which is applied to threaded fasteners to prevent sefd-loosening, leakage and corrosion. Thread lock can be used for all small fasteners such as bolts, nuts and screws where vibration loosening prevention is required:

  • Industrial lubricants, oil, cleaners

  • Metals surfaces like oily steel, aluminium, stainless steel and zinc plated parts

  • Thread fasteners


Which strength of threadlock to use?

This adhesive sealant can come in different strengths:

  • Low Strength - this adhesive is used on screws up to one-quarter of an inch in diameter. These screws include adjustment and calibration screws, gauges, meters and other fastenings that require regular adjustment. Low strength threadlock adhesive allows the fasteners to be easily removed.

  • Medium Strength - this adhesive is used on fasteners up to three-quarter of an inch in diameter. These fasteners are typically used in machine tools and presses, pumps, compressors and mounting bolts. This adhesive allows the fasteners to be removed using hand tools.

  • High Strength - this adhesive is used on fasteners up to one inch in diameter which are used in permanent assemblies such as heavy equipment. High strength threadlocking adhesive provides resistance against a high degree of vibration and offers the highest holding ability.

The RS PRO T43 is medium strength.
