bondura® 4.0 & 6.0

bondura® PIN types 4.0 and 6.0 are the perfect choice when you need to perfectly center two bores, typically in two adjacent plates.

bondura® PIN types 4.0 and 6.0 have been some of our best sellers for many years and are designed to be installed, tightened or retrieved from one side of the adjacent plates.

These version requires sufficient distance on one side to install the pin with sleeve, plate and tightening screw into the bore.


  • The assembly consists mainly of a pin with one conically machined end, one conical end-sleeve to fit the pin end, one end plate, and tightening screws to torque up the assembly
  • When torqueing the pin assembly, the end-sleeve move axially and expand radially until locking the pin assembly to both adjacent bores, as a wedge. This will center the bores relative to each other
  • A torque wrench is required to tighten the screw until the adjacent bores are centered
  • A correctly installed bondura® PIN type 4.0 and 6.0 centers the bores perfectly relative to each other


  • The different parts of the pin assembly can be produced in a range of material qualities with different surface treatments, depending on your specific requirements.
    Our highly skilled engineering team will help select and design the optimal solution for your purpose.
  • All bondura® pin assemblies are wrapped in anti-corrosion film, perfectly protected and prepared for delivery
