Product Details
The Honda OEM K-Series Flywheel Bolt is a genuine factory replacement designed for Honda and Acura K-series engines equipped with compatible manual transmissions. This essential drivetrain fastener secures the flywheel directly to the crankshaft, providing the clamping force required for reliable clutch operation and proper power transfer.
Originally installed in numerous Honda K20 and K24 manual transmission applications, this genuine Honda flywheel bolt features a 12mm threaded diameter and factory-specified design for proper fitment and dependable performance.
Flywheel bolts are critical components in any manual transmission drivetrain. They must withstand engine vibration, rotational forces, and repeated acceleration and deceleration while maintaining a secure connection between the crankshaft and flywheel.
During clutch replacements, flywheel upgrades, engine rebuilds, or transmission swaps, using the correct factory hardware is essential. Damaged, stretched, or improperly tightened flywheel bolts can compromise the flywheel connection and potentially cause serious engine or drivetrain damage.
Manufactured to Honda's original equipment specifications, this genuine flywheel bolt is an excellent choice for maintaining factory-quality engine assembly. Whether you're rebuilding an Acura RSX Type-S, replacing the clutch in your Civic Si, or assembling a high-performance K20/K24 combination, this OEM fastener provides the correct factory hardware for compatible applications.

- When Should Flywheel Bolts Be Replaced?
- Flywheel mounting hardware should be inspected whenever the flywheel is removed for maintenance or drivetrain service.
- Common reasons to replace flywheel bolts include:
- Clutch replacement
- Flywheel replacement or resurfacing
- Engine rebuilding
- Manual transmission conversions
- Damaged or worn bolt threads
- Rounded or damaged bolt heads
- Corrosion or previous improper tightening
- Installation of a compatible aftermarket performance flywheel
- Replacing questionable hardware during clutch or flywheel service helps reduce the risk of fastening problems that could require additional transmission removal.
Installation Notes
- Proper flywheel bolt installation is critical for engine safety and drivetrain reliability.
- Before installation, inspect the crankshaft flange, flywheel mounting surface, and threaded crankshaft holes for damage, contamination, or debris.
- Ensure the flywheel is correctly seated against the crankshaft flange and that all mounting holes are properly aligned.
- Install the new Honda OEM flywheel bolts by hand initially to prevent cross-threading. Tighten the bolts gradually in the sequence specified by the factory service manual.
- Always follow Honda's specified torque, tightening sequence, and thread preparation requirements for your exact engine and flywheel combination.
- Use a calibrated torque wrench and an appropriate flywheel holding tool during installation.
- If the factory procedure specifies thread lubricant or locking compound, use the appropriate product and application method. Do not assume all aftermarket flywheels use the same installation requirements as the factory flywheel.
- For aftermarket lightweight flywheels, racing clutches, or modified crankshaft configurations, confirm that the factory Honda bolt length and fastening specifications remain appropriate.
- After installation, verify that the flywheel is properly seated and all mounting bolts have been secured according to the applicable service specifications.
Note:
- Includes one genuine Honda 12mm K-Series flywheel bolt. Eight bolts are required for a complete replacement on applicable K-series manual transmission engines. The flywheel, clutch disc, pressure plate, pressure plate bolts, and additional drivetrain components are sold separately.
For Honda and Acura enthusiasts replacing a clutch, rebuilding a K-series engine, or assembling a performance-oriented K20/K24 drivetrain, this genuine Honda OEM Flywheel Bolt provides the factory-correct hardware needed for a secure and dependable flywheel installation.

While you already have the trans out when replacing your clutch and flywheel, replace these as well. They aren't that expensive and will give you peace of mind. Honda recommends replacing them anyway too.
Brandon | March 12th, 2021
Great oem quality. Used on my 8.9lb flywheel for 6 speed tsx
William Lee | November 24th, 2020
Honda OEM flywheel bolts. Not really needed but decided to get new bolts in there anyways. You will need a total of 8 to replace them all.
