Compatibility:

✅ Compatible Humminbird Units

  • Solix Series: All Models (Solix 10, 12, 15) - Gen 1, G2, and G3.
  • Onix Series: All Models (Onix 8, 10) - Cross Touch and Non-Cross Touch.
  • Apex Series: Apex 13, Apex 16.
  • Ion Series: Ion 10, Ion 12.

❌ NOT Compatible

Keep your big-screen units locked in place with these genuine Humminbird Replacement Mounting Knobs. Designed for the heavy-duty gimbal brackets of the Solix, Onix, and Apex series, these knobs provide the clamping force needed to prevent your 10-inch+ screens from shifting in rough water.

These are the official factory replacements, featuring the larger thread pitch and wider grip diameter required for Humminbird's top-tier units.

Product Features

  • Heavy-Duty Grip: Oversized tri-lobe design allows for maximum torque to secure heavy head units.
  • Factory Fit: Correct thread pitch for Solix, Onix, and Apex metal gimbals.
  • Sold as a Pair: Includes two (2) knobs to secure one unit.

⚠️ IMPORTANT NOTE: This set includes the Knobs Only.

It does NOT include the rubber washers, split lock washers, or the metal gimbal bracket itself. You must reuse your existing washers.

Frequently Asked Questions

Are these metal or plastic?

They are the factory-standard heavy-duty plastic knobs with a metal threaded insert.

Will these fit my Helix 12?

No. Even though the Helix 12 is big, it uses a smaller bolt thread. You need the "Helix 8-12 Mounting Knobs" instead.

Do I really need the washers?

Yes. The Solix/Apex units are heavy. Without the rubber anti-vibration washers (not included), the unit will slowly tilt down as you drive over waves.
