OKS 250 – White Allround Paste, metal-free

High-temperature paste on ceramic basis for lubricating heavily loaded sliding surfaces.

Areas of application

  • Lubrication of highly stressed sliding surfaces, especially at low slip speeds or with oscillating movements, for example with screwed, mating or bayonet connections made of high-alloy steel or non-ferrous metals
  • Surface separation of temperature-stressed threaded connections, for example at combustion engines and turbines
  • Corrosion protection at screws, pins, bolts, flanges, spindles and fits
  • For stainless-steel connections

Advantages and benefits

  • Economic product solution for users who previously used a wide variety of pastes

Technical specifications

  • Operating temperature: -40 °C → +200 °C/+1,400 °C (lubrication/separation)
  • Press-fit: µ = 0.10, no chatter
  • Four-ball test rig (welding load): 3,600 N
  • Thread friction (M10/8,8): µ total = 0.12


To achieve optimal adhesion remove soiling as well as other lubricants from the thread and sliding surfaces. Use a brush, spatula or similar to apply sufficient OKS 250 to the head or nut contact surface and to the thread. Spray on evenly OKS 2501 spray. The paste will also act as a sealant.
