The Whirlpool WP358237 Agitator Bolt securely attaches the washer agitator to its mounting assembly, keeping it firmly in place during wash cycles. This replacement bolt fits compatible Whirlpool washers and works by threading into the agitator shaft or designated mounting point to maintain a secure connection. A properly fastened agitator can move as intended, circulating clothes through the water and detergent during washing. Replacing a loose, damaged, or missing bolt can restore secure agitator attachment and reduce unwanted movement. Its practical design makes it suitable for routine washer repair and maintenance. The bolt provides a direct replacement solution for securing the agitator and maintaining proper washer function with the required mounting components.
