RedMax 521403001  Knob Bolt

The Bolt, sometimes referred to as a screw or fastener, is one of the most common parts found in outdoor power equipment. Some types of bolts, like a self-tapping bolt or a shear bolt, are very uniquely built for their purpose and must be purchased from the OEM/Manufacturer. Other bolts look identical those you might find in a hardware store. We always suggest purchasing replacement bolts from a genuine OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
