Product Details

The Honda OEM B-Series Flywheel Bolt is a genuine factory replacement designed for Honda and Acura B-Series engines, including popular B16, B17, B18, and B20 applications. This essential drivetrain fastener secures the flywheel to the crankshaft, providing the clamping force necessary for reliable clutch operation and proper power transfer through the manual transmission.

Originally used in numerous Honda and Acura manual transmission applications, this genuine Honda flywheel bolt features a 12mm threaded diameter and factory flange-head design. It is manufactured to Honda's original equipment specifications 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 flywheel hardware is essential. Damaged, stretched, or improperly tightened bolts can compromise the flywheel connection and potentially cause serious engine or drivetrain damage.

Whether you're rebuilding a B18C1 Integra GS-R engine, replacing the clutch in your Civic Si, or assembling a high-performance B-Series engine, these genuine Honda OEM flywheel bolts provide factory-quality fitment and reliability.

When Should Flywheel Bolts Be Replaced?
Flywheel bolts should be inspected whenever the flywheel is removed for maintenance or engine service.
Common reasons to replace the original hardware include:
Clutch replacement
Flywheel replacement or resurfacing
Engine rebuilding
Manual transmission conversions
Damaged or worn bolt threads
Corroded or rounded bolt heads
Previous improper tightening
Installation of an aftermarket performance flywheel
Replacing questionable hardware during drivetrain service can help avoid the need to remove the transmission again to correct a fastening issue.

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 properly seated against the crankshaft flange and that all mounting holes are correctly aligned.
Inspect the new Honda OEM flywheel bolts before installation. Use the correct quantity for your engine and flywheel combination.
Always follow the factory service manual for the correct flywheel bolt tightening sequence, torque specification, and thread preparation requirements.
Install the bolts by hand initially to prevent cross-threading. Tighten them gradually in a crisscross pattern to distribute clamping force evenly across the flywheel.
If the factory procedure specifies thread lubricant or locking compound, use the appropriate product in the specified amount. Do not assume that all aftermarket flywheels require the same installation procedure as the original factory flywheel.
Use a calibrated torque wrench and the appropriate flywheel holding tool during installation.
After tightening, verify that the flywheel is properly seated and that all bolts have been secured according to the applicable service specifications.
For aftermarket lightweight flywheels, racing clutches, or modified crankshaft configurations, confirm that the original Honda bolt length and fastening specifications remain appropriate.

Note:

Includes one genuine Honda 12mm flywheel bolt. Eight bolts are required for a complete replacement on applicable B-Series engines. The flywheel, clutch assembly, pressure plate bolts, and additional hardware are sold separately.

For Honda and Acura enthusiasts replacing a clutch, rebuilding a B-Series engine, or assembling a performance-oriented drivetrain, this genuine Honda OEM Flywheel Bolt provides the factory-correct hardware needed for a secure and dependable flywheel installation.
