Hartmann Lug Bolts are made in Italy to the highest standards and meet QS-9000 quality certification standards as well as ISO/TS 16949 and ISO 9001 TUV certification.


All Porsche vehicles as well as the Audi 4L chassis (2007-2015) Q7 and VW Touareg use a 14mm diameter bolt with a 1.5 thread pitch. OEM wheels use a R14 ball seat bolt with a shaft length of 35mm. Aftermarket wheels typically use a cone seat bolt however some may use a ball seat, the length may also vary depending on the manufacturer.


Hartmann Lug Bolt Specifications:

  • Shaft Diameter: 14mm
  • Bolt Head: 19mm Hex
  • Thread Pitch: 1.50
  • Seat Type: Floating R14 (14mm Radius) Ball

Hartmann Lug Bolt Manufacturing:
Hartmann bolts are constructed from high grade steel and are nickel plated for corrosion resistance.


Determining Lug Bolt Length for Spacers:

Remove one lug bolt and measure the length from the end of the threads to the bottom of the seat, add the spacer thickness to the bolt length. (Stock length + spacer thickness = new bolt length)


Hartmann Lug Bolt Install:

  • Confirm the lugs are the proper length by threading a single bolt in by hand and counting the rotations until seated, you should get 7 rotations. Once seated rotate the wheel slowly to ensure the lug is not contacting any components on the inside of the hub.
  • Install wheels in the air, using the brakes to stop the wheel from turning and torque the lugs to the vehicle manufacturers specified value first in a star pattern, followed by a circle.
  • Re-torque the lugs after 1 week on brand new wheels.
