Reliable micromechanical interlocking of mating surfaces

One of the key aspects of mechanical joints is the shear load capacity. By introducing an interlocking component or surface between the interfaces, the shear strength and holding power of the joint is vastly increased.


The TRD MicroLock surface technology is based on microspikes that engage with the mating surfaces, forming an incredibly strong mechanical interlocking effect.

Characteristics of TRD MicroLock
  • Independant of lubrication
  • High shear load capacity
  • High coefficient of static friction ( even µ > 1.0 )
  • Low variation of µ ( +/- 5% )
  • Outstanding quality control

We develop and produce our own components with TRD MicroLock, as well as offer it as a coating service of your parts.
