Veratron 85MM (3-3/8") Gauge Spinlock

The Veratron 85MM (3-3/8") Gauge Spinlock is a precision fastening component designed for marine and automotive gauge installations where secure, vibration-resistant mounting is essential. Whether you're upgrading your dash cluster, installing aftermarket instrumentation, or rebuilding gauges in a restoration project, this spinlock nut provides the reliable retention needed in high-vibration environments. Mechanics and fabricators rely on quality spinlock fasteners to prevent gauge panel creep and maintain accurate instrument readings over thousands of miles or operating hours.

This 85MM spinlock nut threads directly onto standard gauge shafts, using a nylon-insert locking mechanism to resist self-loosening under continuous vibration and thermal cycling. The white finish offers visibility during installation and maintenance, while the compact design (4 x 2 x 7 inches overall) fits cleanly behind gauge bezels without adding bulk. The lightweight construction (0.1 lbs) ensures minimal strain on gauge stems, preserving accuracy and extending instrument lifespan. Spinlock fasteners distribute clamping force evenly across the gauge mounting surface, reducing the risk of overtightening that can damage delicate gauge mechanisms.

This fastener suits any custom gauge installation, restoration project, or OEM gauge replacement where factory spinlock nuts are damaged or lost. It works seamlessly with 85MM-diameter gauge bezels common in automotive, marine, and industrial instrument clusters. Installation is straightforward: simply thread the nut onto the gauge shaft by hand, then tighten with a wrench until snug—no specialized tools required. Sold individually, this spinlock nut is an economical backup component for garages, fabrication shops, and serious enthusiasts maintaining custom instrument panels.
