Are the roll pins, part number STD572512, shear pins?

I need roll pins but am in the middle of a large snow storm. Can I use any nut and bolt for now so the blower works or am I risking a shaft? Are roll pins shear pins?

The roll pins that hold the impeller to the shaft are shear pins.

You can use 2 bolts instead of the roll pins. There is some risk involved. Be sure the bolts you use are not hardened bolts.

You will probably have to remove the auger and gearcase from the auger housing to replace the shear pins with bolts.
