Genuine Honda Flywheel Bolt (90011-PNA-B00) - K-Series
These are the bolts holding your flywheel to the crankshaft, and they're not a part to improvise on. They're clamping a spinning mass to the back of your engine against enormous cyclic load, and a flywheel bolt that fails does spectacular damage on its way out. This is the genuine Honda part, and it covers essentially the entire K-series range.
You Need Eight, Sold Individually
Read this before you check out. These are sold one at a time, and most K-series applications use eight bolts. Order one and you'll be seven short with the transmission already out.
Count what your engine takes and order accordingly. It's a small thing to get wrong and an extremely annoying thing to discover mid-job.
Don't Reuse Your Old Bolts
The most important advice on this page. Flywheel bolts are torque-to-yield, meaning they're designed to stretch permanently as you torque them down. That controlled stretch is what generates the clamping force holding the flywheel to the crank.
A bolt that's already been stretched once has done that job. Reuse it and you're not getting the clamping load the design calls for, which means a flywheel that can work loose. On a part spinning at engine speed with your clutch bolted to it, that's not a risk worth taking to save a few dollars.
You're already pulling the transmission, which is nearly all the labor. New bolts are the cheapest part of the entire job.
Get Them In While You're There
Reaching flywheel bolts means the transmission is out and the clutch is off. That's a full day of work whether you're paying a shop or doing it yourself, so anything you can replace with that access should get replaced.
If you're doing a clutch, a flywheel, or a rear main seal, add these to the order. Same goes for an engine build, since there's no reason to put twenty-year-old torque-to-yield hardware back into a fresh motor.
Torque Them Properly
Look up the torque spec and the tightening sequence for your specific engine and follow both. Flywheel bolts get torqued in a cross pattern in stages, not one at a time to full value, and getting that wrong means uneven clamping.
Check whether your application calls for thread locker too, since that varies and it's worth knowing before the flywheel is on.

Who Should Grab These
This is for anyone doing a clutch, a flywheel, or an engine build on a K-series who wants the job done properly. They're inexpensive, they're the correct genuine part, and they're the wrong place to economize given what's bolted to them. Count your eight, torque them to spec, and close it up once.
