Where to purchase a new central bolt for a Honda HRR216VKA blades? Links please!

so you sheared the bolt and the key. No way is that crankshaft not tweaked as a bend or twist. The key flat side usually goes into the crankshaft. Make sure the sparkplug wire is out when you work on it. Torque the bolt to specs. Then make note where one end of the blade is close to the edge of the mower housing, rotate it 180 degrees to be sure it is in the same spot. If the mower runs poorly or won't start, suspect the flywheel key may be sheared too. If it vibrates badly, then the crankshaft is warped. If that is the case, you may find another model with the same engine as a donor on FB Marketplace.

KEY, WOODRUFF (3/16X5/8)

Worked on a lot of Honda mowers and have never seen that bolt broken.
As an aside I had to retire for medical reasons after having torn a mower apart for engine issues. Did not get it assembled as they were waiting on parts. Once parts came in I got a call asking about the crankshaft/key. They asked how can we get this woodruff key to work in the crankshaft, it is cut for a straight key? I answered "turn the crank 180". They did and said "OK i see"

Thank you. The mower works fine despite not installing this toenail clipping (key).
