Parts Desk Insights
Best Use Case: Ideal for replacing worn lock washers on marine hardware where corrosion resistance and secure fastening matter. Pair with a matching 5/16" bolt and confirm you’re using the correct stack-up with any washers already in the assembly.
Common Issues: Common installation issues include using the wrong hardware size (leading to poor contact), stacking incompatible washer types, and reusing hardware that has already loosened. When servicing, check the mating surfaces and verify the correct washer location in the fastener stack.
