Veratron 110MM (4-3/8") Spinlock Nut f/AcquaLink® & ViewLine Gauges

The Veratron 110MM (4-3/8") Spinlock Nut for AcquaLink® & ViewLine Gauges is a precision marine instrument fastener engineered for secure, vibration-resistant gauge mounting on vessels operating in demanding saltwater and freshwater environments. Designed for marine technicians, boat builders, and fleet maintenance personnel, this spinlock nut eliminates gauge drift caused by engine vibration and hull movement—critical for maintaining accurate bilge, fuel, water, and coolant level readings during extended operations. Veratron's marine-grade fastening solutions are trusted across commercial fishing, military patrol craft, and recreational boating platforms where instrument reliability directly impacts operational safety.

This spinlock nut features a mechanically-locking design that prevents self-loosening through nylon insert technology, a proven standard in marine hardware. The white finish resists corrosion and maintains visibility during installation and service checks in engine compartments with poor lighting. At 1 pound, the nut's robust construction accommodates the 110MM panel cutout diameter of Veratron's ViewLine and AcquaLink gauge systems, ensuring flush panel mounting and load distribution that protects the gauge connection from mechanical shock and thermal cycling common in marine powerplant environments. The nylon insert mechanism requires no additional washers or lock washers, simplifying installation and reducing potential mounting errors.

Marine electricians and vessel maintenance crews benefit most from having spare spinlock nuts on hand, as replacement during gauge service eliminates downtime associated with fastener failure or corrosion. This component is sold as an individual unit, allowing operators to stock replacement inventory or upgrade existing gauge panels. Compatible exclusively with 110MM ViewLine and AcquaLink gauge series, this spinlock nut should be installed hand-tight plus one-quarter turn with a properly-sized wrench to achieve secure seating without overtightening, which could damage the nylon insert or gauge panel threads.
