Mercury Washer (12-55073A2)

The Mercury Washer is a complementary fastening component in marine engine and propulsion systems that ensures fasteners operate with the correct tightness and securely. The Mercury Washer (12-55073A2) helps distribute the load evenly in bolt and nut connections, preventing loosening, reducing surface deformation, and increasing assembly safety. Correct washer usage is critical for system health, especially in areas with high vibration, such as engines and gears.

This washer, coded 12-55073A2, maintains its shape against high squeezing forces and continuous vibration thanks to its durable metal construction. Washers that are worn, bent, or have a damaged surface over time can lead to loosening at connection points, increased noise, and damage to secondary parts. Therefore, the condition of the washers must be checked during maintenance and repair procedures, and they should be replaced if necessary.
