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.
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?
The Tenax fastener stud acts as the fixed anchor point for the Tenax quick-release fastening system.
Its primary functions include:
- Providing a secure mounting point for the Tenax fastener.
- Holding trim and covers firmly in place.
- Allowing quick installation and removal.
- Maintaining correct alignment of attached components.
- Reducing movement and vibration.
- Preserving the original appearance of the fastening system.
The precision profile ensures reliable engagement with the corresponding Tenax fastener cap.
Why Replace the Tenax Fastener Stud?
Although small, Tenax studs are exposed to years of use and environmental conditions.
Common reasons for replacement include:
- Corrosion or worn finish.
- Damaged or worn locking profile.
- Bent or broken stud.
- Loose mounting.
- Missing original hardware.
- Restoration of trim or tonneau covers.
- General refurbishment of fastening systems.
Replacing worn studs restores the correct operation of the complete Tenax fastening system while improving the appearance of your Porsche.

Position: Body mounting point for convertible top or tonneau cover Tenax fasteners
Sold as: Individual fastener stud, 6 required per vehicle
The Tenax fastener stud acts as the fixed mounting point for Tenax snap fasteners used on convertible top covers or protective tonneau covers. When paired with the matching Tenax cap, it creates a secure locking system that holds fabric covers firmly in place while still allowing quick removal when needed.
Replacing worn or damaged studs restores the proper attachment points for convertible covers and helps maintain the original functionality and appearance of the vehicle’s roof system.
Function
• Convertible Cover Mounting: Provides anchor point for Tenax snap fasteners
• Secure Fastening: Keeps tonneau or roof covers firmly attached to the body
• Quick Release Design: Allows easy removal of covers when required
• Durability: Chrome-plated brass/steel construction resists corrosion and wear
Tenax studs are exposed to weather, repeated use and vibration. Over time they may corrode, loosen or become damaged, which can prevent convertible covers from fastening securely. Installing a new OE Match stud restores the original fastening system and ensures that covers remain securely attached while preserving the classic Porsche appearance.
Replace the Tenax fastener if you notice:
• Loose or missing convertible cover fasteners
• Corrosion or damage to the stud
• Difficulty attaching Tenax caps
• During convertible top or tonneau cover restoration
