Important Notes

• This is a shear bolt, not a standard general-purpose fastening bolt

• Compatibility varies by snow blower model and auger assembly configuration

• Confirm fitment using the equipment model, product number, and applicable parts diagram

• Verify the required bolt length, shoulder configuration, thread size, and shear characteristics before ordering

• Do not substitute a standard bolt or higher-strength fastener for a specified shear bolt

• Using an incorrect fastener may prevent proper shearing and result in damage to the auger drive system

• Confirm whether retaining nuts, washers, or other mounting hardware are included or must be purchased separately

• Inspect the auger shaft, mounting holes, and related drive components after a shear bolt breaks

• Remove any obstructions and determine the cause of shear bolt failure before installing a replacement

• Follow the manufacturer's recommended installation and tightening procedures

• Shut down the engine, remove the ignition key, disconnect the spark plug, and allow all moving components to stop before performing service

• Never attempt to clear a snow blower obstruction while the engine is running

• Keep replacement shear bolts available for maintenance during the snow removal season
