What This Product Does:

• This bolt secures the clutch pressure plate to the flywheel ring gear or flywheel assembly in a manual transmission vehicle. It takes high torque loads as the clutch engages/disengages and transmits engine power through the drivetrain.
• Ensuring a correct, tight, and properly-torqued fastener in this location is critical — the bolt must handle rotational forces, vibration, clutch engagement loads and thermal cycles.
• A correct bolt helps maintain clutch alignment, prevents loosening under load, and safeguards against failure of the pressure plate mounting.

When / Why You Should Replace It:

• Because this is a high-stress and safety-relevant fastener, it is common practice to replace it whenever the clutch pressure plate is removed or the flywheel is serviced.
• The vehicle is undergoing a clutch replacement or flywheel/service operation.
• The bolt shows visible wear, corrosion, threads damaged or previously reused beyond specification.
• The bolt is the original hardware and you are doing a rebuild — replacing ensures reliability.
• Using a reused or incorrect bolt may risk loosening, bolt fatigue, or failure, which can lead to clutch or flywheel damage and significant repair cost.

Why Replacement Matters:

• Because the bolt is part of the clutch mounting and load-bearing system, using the correct OEM specification ensures the right material strength, thread engagement, length and fit.
• When the clutch pressure plate is removed, the clearances, torque spec and fasteners all matter — using the correct bolt supports safe operation and avoids premature failure.
• For high-value vehicles and rebuilds, ensuring all hardware is correct helps ensure durability, quality and resale-value.

This OE Match exhaust strap bolt is a direct replacement for the original Porsche fastener used to mount the muffler retaining strap. Designed to factory specifications, it features a pan-head M8 x 50mm configuration, ensuring proper fitment and secure fastening

This component is specifically used in conjunction with the exhaust muffler strap (e.g. 99311111907) to hold the silencer firmly in place, maintaining correct exhaust alignment and structural integrity.

This bolt secures the muffler strap to the mounting point, ensuring the exhaust silencer remains properly positioned. It helps prevent movement, vibration, and misalignment of the exhaust system during operation.

Function
•  Secures exhaust muffler strap to chassis mounting point
•  Maintains correct positioning of exhaust silencer
•  Prevents loosening under vibration and heat cycles
•  Supports stable and secure exhaust system mounting
•  Ensures long-term fastening reliability in high-temperature conditions

Exhaust fasteners are exposed to extreme heat, moisture, and road debris, which can cause corrosion, seizure, or thread damage. A worn or incorrect bolt may lead to loose exhaust components, increased vibration, or misalignment. Replacing it ensures secure fastening and proper exhaust system stability.

When to replace
•  During exhaust or muffler strap replacement
•  Bolt is corroded, seized, or damaged
•  Loose or rattling exhaust components
•  Signs of thread wear or stripped head
•  Preventative replacement during exhaust maintenance
