Do harmonic balancer bolts come with washers?

Harmonic balancer bolts typically do not come with washers, as they are designed to be used without them. The bolts are usually designed to provide a secure fit against the harmonic balancer and the crankshaft without the need for additional hardware. However, it's always best to consult the manufacturer's specifications or service manual for the specific vehicle to determine if washers are recommended for that application.
