The Perko 0493DP999L Cover Bolt is a direct-fit replacement for Perko raw water strainers in sizes 8, 9, and 10. If your strainer cover is loose or damaged, this part restores full function and a tight seal. It’s built for boats where water flow and system pressure must stay controlled without leaks.
This bolt is made from marine-grade materials, tested for saltwater conditions. The threads hold strong against vibration and engine movement. It keeps the strainer cover secure and locked, even when your engine runs under load.
No need for custom tools. The bolt installs using basic hand tools already found on most boats. It's designed to match the original factory fit, so no adjustments are needed. This is a must-have spare for routine maintenance or emergency repairs.
Whether you're outfitting a commercial vessel or a weekend runabout, the Cover Bolt keeps your system sealed and running right. It matches Perko’s high standards in strength, fit, and finish.
