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.
