Benefits for your application


– Reliable screw connection ensured by constant and sufficient preload force
– Easy release also after long time at high temperature
– Approved in acc. with VW-TL 52112 and Ford tox. No. 138624





Klüberpaste HEL 46-450 is a black hot screw paste for highalloy steels. It contains fully synthetic polyalkylene glycol and ester base oils and a combination of inorganic solid lubricants.

Klüberpaste HEL 46-450 is suitable for a temperature range between -40 °C and 1000 °C. In the normal temperature range (i.e. below 200 °C) it shows good anticorrosion behaviour and good water resistance. Above 200 °C it acts as a dry lubricant.



Screw paste for conventional and high-alloy steels (Cr-Ni steels) up to 1000 °C.

Lubricating and assembly paste for connections in hot air ducts (e.g. automotive exhaust systems). For connecting elements in turbochargers and compressors.

**High-temperature screw test

The test was performed acc. to VW-TL 52112


– Bolt: DIN 931-2
– Material:1.4989
– Nut, material: 1.4923


The nuts were preloaded with 70 Nm and stored at 750 °C for 100 hours. After this period a low release torque was measured.

Application notes


It is important to clean and degrease the contact surfaces thoroughly before applying Klüberpaste HEL 46-450. A thin layer of paste is then applied by brush, leather cloth or plastic sponge.

Klüberpaste HEL 46-450 spreads easily over the entire surface and thus prevents excess lubrication.

Close container immediately after use in order to prevent contamination.

The friction values indicated on page 2 in the Section Product Data were determined with two different materials. Other materials/surfaces have to be checked accordingly.
