Ring Terminal #10 Hole Non-Insulated 12-10 20pk

The Ring Terminal #10 Hole Non-Insulated 12-10 20pk by ALLSTAR PERFORMANCE provides a reliable foundation for custom electrical systems in automotive builds, restorations, and performance modifications. These bare copper terminals are essential for anyone rewiring a classic car, upgrading a charging system, or installing auxiliary lighting and accessories. Non-insulated ring terminals excel in high-vibration environments where a solid, corrosion-resistant connection is non-negotiable—particularly in engine bays and frame grounds where thermal cycling and moisture exposure demand durability.

Designed for 12–10 AWG wire gauges, each terminal features a #10 bolt hole that crimps securely onto stripped wire ends, creating a low-resistance junction capable of handling sustained current flow without voltage drop. The non-insulated design allows direct metal-to-metal contact with fasteners, maximizing conductivity and reducing impedance in ground straps, battery cable connections, and distribution block terminations. ALLSTAR PERFORMANCE's cold-formed copper construction resists oxidation and maintains consistent contact resistance across repeated thermal cycles, critical for engine harnesses exposed to underhood heat and moisture.

These terminals suit restoration electricians, performance shop technicians, and DIY builders upgrading alternators, starter circuits, and ground distribution systems. The 20-pack quantity covers multiple circuit points in a typical vehicle rewire or component upgrade, making bulk stock economical for shops. Installation requires a proper crimping tool sized for 12–10 gauge wire to ensure full contact within the terminal barrel; undersizing the crimp results in poor connection and potential voltage loss or overheating under load. Compatible with any #10 bolt stud, these non-insulated terminals integrate seamlessly into custom battery cables, fused distribution blocks, and grounding networks.
