Ring Terminal 5/16 Hole Non-Insulated 16-14 20pk

The ALLSTAR PERFORMANCE Ring Terminal 5/16 Hole Non-Insulated 16-14 20-pack delivers reliable electrical connections for automotive and motorsports wiring applications. Constructed from tin-plated copper, these non-insulated ring terminals provide excellent conductivity and corrosion resistance, making them ideal for high-current circuits where secure, low-resistance connections are critical. The 5/16-inch hole diameter accepts standard fasteners found on battery posts, alternators, starters, and distribution blocks.

Designed for 16–14 gauge wire, these terminals crimp securely onto solid or stranded copper conductors, creating a permanent connection that resists vibration-induced loosening common in motorsports environments. Tin plating prevents oxidation during storage and in humid conditions, ensuring consistent contact resistance when installed. The non-insulated design allows direct metal-to-metal contact with battery terminals and electrical components, eliminating the contact resistance penalty that insulated sleeves introduce—a critical advantage in high-performance ignition and charging systems where voltage drop must be minimized.

This 20-piece set addresses the needs of engine builders, race teams, and restoration specialists who require multiple connection points without excess inventory. Whether upgrading a classic hot rod's electrical harness, building a competition engine bay, or establishing reliable ground points in a high-horsepower application, having pre-sized terminals on hand reduces fabrication time and ensures consistency across all connections. The compact size and straightforward design integrate seamlessly with existing terminal crimpers and installation tools.

Non-insulated terminals are standard in professional automotive electrical work precisely because they deliver superior conductivity and heat dissipation compared to insulated variants. For ground distribution, battery interconnects, and high-amperage feeds where performance margins matter, these ALLSTAR terminals represent the baseline choice in quality motorsports shops and fabrication facilities.
