Purpose of Snow Blower Shear Bolts

What is the purpose of shear bolts?

Shear bolts serve two purposes:

  1. Shear bolts fasten the auger to the auger gearbox shafts.
  2. Shear bolts prevent damage to the auger and/or gearbox in the event the auger contacts a solid object during snow removal.

These shear bolts are classified as a grade 2 bolt, which are hard enough to maintain auger rotation, yet soft enough to shear if the auger is prevented from rotating.

Replacement bolts are available through a local Brute Service Center.
