The Tenax fastening system has been trusted for decades in automotive applications thanks to its secure locking mechanism, durability and ease of use. The stud forms the fixed mounting point that the Tenax fastener cap locks onto, providing a reliable connection while allowing quick removal whenever required.

Size: 4.2mm x 16mm
Finish: Black

Over time, original studs can become corroded, damaged or worn through repeated use, reducing the effectiveness of the fastening system and detracting from the appearance of the vehicle. Manufactured to OE Match standards and finished in black, this replacement stud restores both functionality and the correct period appearance.

What Does the Tenax Fastener Stud Do?

  • Allowing quick installation and removal.
  • Maintaining correct alignment of attached components.
  • Reducing movement and vibration.
  • Preserving the original appearance of the fastening system.
