Shear Bolt and Nut 52100100

This shear bolt and nut, also known as the shear bolt assembly, is sourced from the original manufacturer, and it is guaranteed to fit your snowblower. Each assembly includes one metal shear bolt and one metal nut, located at the connection point between the auger and gearbox/shaft. It is a safety mechanism designed to protect the snowblower auger from damage caused by sudden stops or excessive resistance. When the auger encounters a blockage or excessive load the shear bolt will break thereby preventing more severe damage to the gearbox. Once the bolt is sheared, it will need to be replaced. The bolt will also need to be replaced if it is bent or worn down, as a faulty shear bolt can result in damage to the auger, gearbox, and motor, as well as reduced equipment ability to throw snow, and increased safety risks. Use a socket or wrench to unthread the nut and remove the broken shear bolt. Align the new shear bolt with the mounting hole and secure it with the new nut. Note that this is a common repair and it is best to have several spare shear bolts and nuts on hand.
