microGLEIT® DF-Series
Dry Film Lubricants for Threaded Connections

microGLEIT® is the leading supplier of dry film lubricants for fasteners. Intensive development work and the experience of many years of practice with products and processes result in a wide range of reliable “friction adjusters“.

  • Lubricants are indispensable for adjusting the coefficient of friction to desired values and narrowing down the standard deviation of the friction values of modern connection elements.
  • Good choice of the product and proper processing is influencing the layer quality – ideally synergies are achieved here.

microGLEIT® DF dry films are mostly water-based lubricant systems; they contain e.g. PE (polyethylene) and partly additives such as PTFE or wax.

  • After application this dry films build thin, transparent layers with a typical thickness of 1 to 5 μm.
  • For connection elements of all kinds this thin layer warrants a defined, constant coefficient of friction μges in a range of 0,08 to 0,16, depending on application and product. (Friction values μges according DIN EN ISO 16047)
  • Basic principle:
    No threaded connection without proper lubrication!

microGLEIT® dry film lubricants are used on threaded connections in almost any industry segment, such as:

  • bolts and nuts with metric threads (e.g. according ISO 4014, DIN 931, 933 etc.),
  • wood construction screws (e.g. SPAX®),
  • stainless steel bolts and nuts,
  • almost any threaded connection in automotive industries,
  • thread forming and self-tapping screws,
  • and many more..,

microGLEIT® dry film lubricants are suitable as topcoating for all known surfaces on bolts and nuts, such as:

  • phosphatizing
  • galvanic zinc (including all chromate coatings (yellow, blue, black or olive)
  • zinc-nickel and zinc-iron coatings
  • zinc-flake coatings.

microGLEIT® dry film lubricants are characterised by very good film formation and excellent processing capability during application. microGLEIT® offers not only top products but also appropriate process knowhow.
