This chain adjustment tensioner bolt (bar adjustment bolt) is sold individually. The bar adjustment bolt works with the adjuster gears and the adjustment pin to alter the tension on the cutting chain. The gears rotate the bolt, and as it turns, it pulls the adjustment pin, which moves the bar. The bolt can strip over time or if the chain is consistently over tensioned. This is a manufacturer-approved part designed to be a direct replacement for the original.
