Product Description
Mitchell 81709 Side Plate Screw – Genuine Replacement Part
The Mitchell 81709 Side Plate Screw (also known as a Cover Plate Screw) is a critical hardware component for Mitchell’s large-frame conventional and saltwater trolling reels. These screws are responsible for securing the side plates (housing covers) to the main frame, ensuring that the internal drivetrain and spool remain protected and properly aligned under the high-torque conditions of offshore fishing.
Because these reels are often exposed to heavy salt spray and high vibrations from boat travel, side plate screws can become corroded, vibrated loose, or stripped over time. Replacing damaged hardware with this genuine-spec screw is essential to maintain the structural integrity and water-resistant seal of your vintage Mitchell 600 series reel.

OEM Fit & Finish: A direct replacement that maintains the original aesthetic and mechanical standards of the Mitchell 600 series.
Maintenance & Lubrication Recommendation
Side plate screws are the most common victims of "seizing" due to salt crystal buildup. To ensure you can always open your reel for maintenance, we strongly recommend using Deuthlon products during installation:
-
Deuthlon Reel Grease: Apply a small amount to the threads of the 81709 screw before inserting it. Its "Aqua Shield" technology creates a waterproof barrier that prevents galvanic corrosion and keeps the threads from "freezing" into the frame.
-
Deuthlon Reel Oil: For extra protection in extreme conditions, a light wipe of oil on the screw head after installation can help shed water and prevent surface rust from forming in the screw's drive slot.
