Product Description
Mitchell 81681 Main Screw | Fits 710 & 710A Automatic Fly Reels
Ensure the structural security of your vintage fly reel with the genuine Mitchell 81681 Main Screw. This specialized fastener is a critical hardware component for the Mitchell 710 series, designed to hold the housing and internal spring motor assembly in precise alignment. Because automatic fly reels operate under significant internal spring tension, using the correct factory-spec screw is essential for safety and mechanical reliability.
Crafted from high-tensile, corrosion-resistant steel, this main screw is a direct replacement for stripped, rusted, or lost fasteners that can compromise the integrity of your reel's chassis.

Installation & Maintenance
The main screw is often the first point of contact for moisture, which can lead to "seizing" over time. When performing a repair or full restoration, we recommend the following Deuthlon lubrication protocol to protect your hardware:
-
Deuthlon Reel Gear Grease: Apply a very small amount of grease to the threads of the 81681 Main Screw before installation. This acts as an anti-seize agent and creates a waterproof barrier, preventing galvanic corrosion between the screw and the aluminum housing.
-
Deuthlon Reel Power Oil: Use a drop on the external screw head after installation to help shed water and maintain the classic finish of your reel's hardware.
Why Choose Genuine Mitchell Hardware?
Unlike universal hardware store screws, the Mitchell 81681 features the exact thread pitch and length required to seat fully without bottoming out or damaging the internal motor housing. Using the original part ensures that the housing remains "salt-tight" and that the internal mechanics do not vibrate loose during the rapid line retrieval for which the Mitchell 710 is famous.
