Reliable micromechanical interlocking of mating surfaces

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

The MicroLock technology can be used on both sides of a thin component or as a gripping surface on one side of a tool.


More detailed information on our MicroLock Discs for metric size bolts and screws: Datasheet – TRD MicroLock Discs.

We offer the following MicroLock technologies:

MicroLock S1 for all steel and cast iron counterparts

MicroLock S2 for aluminium, composite and polymer counterparts

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 ( 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.
