Product Description
Mitchell 81008 Hex Nut – Essential Rotor Retaining Hardware
Secure the heart of your vintage Mitchell spinning reel with the Mitchell 81008 Hex Nut. This specialized fastener is the primary retaining nut that locks the rotor assembly onto the pinion gear or main axle (depending on the specific model architecture). A secure, vibration-free fit at this junction is critical for maintaining perfect rotor balance and preventing mechanical play during high-speed retrieves.
Over decades of service, these nuts can become rounded, stripped, or lost during maintenance. Replacing a damaged nut with the genuine 81008 model ensures the correct thread pitch and flange width, providing the necessary clamping force to keep your rotor perfectly centered.

Maintenance & Installation Tips
Because the rotor nut is subjected to constant rotational torque and potential moisture trapping, proper lubrication during installation is vital:
-
Thread Protection: Apply a small amount of Deuthlon Reel Grease to the threads of the pinion gear before threading the 81008 nut. This acts as a anti-seize agent, preventing the nut from "freezing" due to oxidation or salt exposure.
-
Exterior Coating: After tightening, apply a light film of Deuthlon Reel Oil to the face of the nut to help shed water away from the main bearing or pinion support area.
-
Proper Torque: Use a properly sized hex wrench to avoid rounding the corners of the nut. Ensure it is snug, but do not over-tighten, as this can stress the pinion gear.

Why Choose This Part?
-
OEM Thread Match: Guaranteed to fit the specific metric threads used in French-made Mitchell pinion gears.
-
Vibration Dampening: Precision-flat base ensures even pressure against the rotor, reducing "wobble" during fast retrieves.
-
Corrosion Resistance: High-quality material selection prevents the nut from rusting and bonding to the internal drive train.
