It is an authentic OEM sourced part that is specially designed for Husqvarna chainsaws. This replacement screw is an important component of the chain tension mechanism that allows user to easily adjust tension of the chain by turning the screw. If the chainsaw bar doesn’t adjust when you turn the tension screw usually either the screw or the pawl is worn or damaged. Please note one durable metal tension screw is included per order. Replacing this part is a simple task that should only require a screwdriver set.
