Compatibility Note
Installation Tip: This is an M10 bolt that typically requires a 17mm socket wrench for installation. It is strongly recommended to use a small amount of thread-locking fluid on the bolt, even if the OEM part is pre-coated, to ensure the bolt remains tight against the high vibrations of the spin cycle. Always unplug the washer before disassembly.
