Ring Terminal 1/4in Hole Non-Insulated 12-10 20pk

The ALLSTAR PERFORMANCE Ring Terminal 1/4in Hole Non-Insulated 12-10 20pk is a professional-grade electrical connector designed for automotive, marine, and motorsports wiring applications where secure, corrosion-resistant connections are essential. This 20-pack of tin-plated copper ring terminals accommodates 12–10 gauge wire and features a 1/4-inch stud hole, making them compatible with standard fastening points found in engine bays, battery terminals, grounding systems, and electrical distribution blocks.

The tin-plated copper construction provides superior conductivity while resisting oxidation and corrosion—a critical advantage in high-vibration environments and applications exposed to moisture or salt air. The non-insulated design allows direct metal-to-metal contact with fasteners, ensuring low-resistance connections suitable for high-amperage circuits. The 12–10 gauge wire range covers common power and ground circuits in vehicles, equipment, and control systems, while the consistent 1/4-inch hole diameter ensures repeatable installation across multiple connection points.

Technicians, fabricators, and DIY builders rely on non-insulated ring terminals like these for engine harnesses, alternator and starter connections, battery banks, and custom wiring in race cars, trucks, boats, and industrial equipment. The 20-pack quantity reduces per-unit cost when outfitting multiple circuits or maintaining spare inventory. ALLSTAR PERFORMANCE is recognized in the motorsports and performance automotive sector for dependable electrical components, making these terminals a trusted choice for builds where connection reliability directly impacts performance and safety.
