Connecting Elements

Connecting elements made by ESKA feature special parts for definite applications in automotive industry and are manufactured according to customer drawings.

One of the core competencies is covered here by high-strength Aludrive® fasteners which are preferably used on the car powertrain to connect light-metal components made from aluminum and magnesium. These bolts are produced by ESKA in a worldwide unique and fully interlinked Aluminum Centre at the Chemnitz location whereby maximum productivity along with utmost process stability and quality are ensured.

Moreover, ESKA is also licensee of CONTI Fasteners AG and supplier of the globally spread TAPTITE® thread-rolling fasteners for direct screwed joints in metals and plastics. ESKA supplies such commonly used geometries as TAPTITE 2000®, TAPTITE® PRO®, FASTITE 2000®, REMFORM® II™, POWERLOK® II™ as well as other special threads with surface systems adapted on request to the relevant application for  flawless and process-safe tightening.

Standardized screws and bolts are produced and delivered by our company on demand. However, they can only complement the product range to enable the customer to purchase all connecting elements from one hand and, thus, to keep the number of suppliers as small as possible.




The product range of connecting elements is defined as follows:


  • thread or shank diameter M4 up to max. M40
  • maximum head diameter 50 mm
  • length 6 mm to 220 mm


Boron-alloyed steel grades (e.g. 23MnB3), low-alloyed (e.g. 34Cr4) and alloyed steel grades (e.g. 40CrMoV4.7) and aluminum are used as materials. In accordance with the definite application, the material can be selected together with the customer.
