The threads are 12 x 1.0 mm, but I don't recall how long they are. I also believe they have a 12 point head on them.

1. You are not suppose to reuse the stock bolts more then once.
2. You should be torquing the bolts down.
3. You should be using thread locker on the bolts
4. This also goes for the PP
5. ARP won't be any less prone to backing out if not installed correctly to start (other then being new)

1. It doesnt say in the manual that you cannot use the stock bolts more then once.
2. Yes I have followed all the torque specs
3. Many ppl suggested not to use locktite
4.
5. True but ARP should can withstand more stress in the long run

1. I am fairly certain the Honda Shop Manual states to replace both the flywheel and PP bolts, I will confirm if needed. Either way it is good practice to replace critical hardware when using OEM.
2. Are you following the torquing pattern?
3. Red locktite would be bear but useable, but blue would be adequate. No harm in using locktite.
4.
5. Flywheel is not under tension so there is little no to benefit in using them for this application. You aren't pulling on them but pushing against them. What they do offer in most cases is the ability to remove and reinstall without replacement. Alot of OEM hard ware is Torque to Yield (not saying they are in this applicaiton) which makes them really one time use. Can you use them again? Yeah they will screw in and tighten but don't be have the same because they already yielded.

Just trying to point out that something is missing with what you and your friend are doing. Replacing them with ARP hardware MAY solve the issue or not. Understanding what you are doing and what you are using is key. I can't recall EVER seeing a thread with someone having issues with the flywheel bolts loosening up after a clutch install.

I would think the focus would be to understand why that is happening instead of just throwing money at it hoping it will solve it. It may but was it because you used new hardware, you torque it in the right pattern, etc...

Not sure what ARP bolts would run but you can get all new OEM bolts for under 40... Quick search for ARP 12mm X 1.5 bolt found something similar for 19bux a pop... But I am unsure if the shouldered portion of the bolt is important for locating also


I know the bolt size is 12X1.0 but that only yields results for B series motors and those are 75ish a set, but I do not think they are long enough.
