Minelab Large Coil Hardware Nut, Bolt & Washer Set for FBS Metal Detectors

The Minelab Large Coil Hardware Set is a replacement mounting kit for FBS metal detectors, including the CTX 3030, E-TRAC, and Explorer series. FBS detector owners working mineralized ground or saltwater beaches rely on secure coil attachment to maintain signal stability, and this hardware set restores factory-spec mounting when the original fasteners wear or strip. The kit contains the nut, bolt, and washer needed to mount large coils on Minelab FBS platforms. Minelab manufactures this hardware to the same tolerances as the original equipment, ensuring proper thread engagement and coil alignment.

What's Included with the Large Coil Hardware Set

• Minelab Large Coil Hardware nut
• Bolt
• Washer

Why FBS Detector Owners Keep Spare Hardware

• Factory-spec thread pitch and material composition prevent cross-threading and ensure the coil seats flush against the lower rod, eliminating wobble that degrades target ID accuracy in trashy sites.
• Field-replaceable fasteners let you swap coils mid-hunt without returning to the vehicle, critical when switching from a large open-field coil to a smaller high-trash coil as site conditions change.
• Minelab-manufactured hardware matches the corrosion resistance of the original equipment, maintaining reliable coil connection in saltwater environments where aftermarket fasteners often fail within a season.
• Spare hardware eliminates the risk of ending a hunt early due to a stripped bolt, particularly valuable on multi-day trips to remote detecting sites where replacement parts are unavailable.

Secure Coil Mounting for CTX 3030 and E-TRAC Owners

A loose or worn fastener introduces micro-movement between the coil and lower rod, which the detector interprets as ground noise or false signals in mineralized soil. The Large Coil Hardware Set restores the rigid connection that FBS platforms need for accurate ferrous/conductive target ID. Our team runs this hardware on CTX 3030 and E-TRAC detectors in wet sand and iron-laden Civil War sites, and the Minelab-spec bolt torque holds the coil stable through full hunt days without requiring mid-session retightening. Detectorists working Minelab CTX 3030 metal detector – detectors, coils, & accessories in high-trash parks benefit from the ability to swap between large and small coils quickly, and keeping a spare hardware set in your pouch means you're never sidelined by a lost or damaged fastener.
