RedMax 539976988 Hair Pin, #2

The purpose of the Pin is to fasten objects together, typically as a shaft meant to be inserted into a slot. If subjected to substantial torque, many pins are designed to break in order to protect other components. Some types of pins, like a shear pin, are very uniquely built for their purpose and must be purchased from the OEM/Manufacturer. We always suggest purchasing replacement pins from a genuine OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
