Shear pins for metering pumps and other applications are manufactured by us. We are also offering a pin for reel guide box 930 and high tensile cotter pin in this range. Shear bolts are another name for these shear pins. It's a fragile bolt that holds the auger to the auger shaft. This connection permits the augers to revolve, gather snow, and transfer it to the impeller fan, where it is thrown down the chute. If a big item gets stuck between augers and the housing, the shear pins will break to keep the gearcase safe.
