Ring Terminal #8 Hole Non-Insulated 12-10 20pk

The Ring Terminal #8 Hole Non-Insulated 12-10 20pk from ALLSTAR PERFORMANCE is an essential electrical component for custom automotive wiring, engine builds, and restoration projects. As a mechanic or DIY enthusiast upgrading your vehicle's electrical system, you'll rely on these terminals to create secure, low-resistance connections between battery cables, alternators, starters, and distribution blocks. Non-insulated ring terminals are the professional choice when space is tight or when you need direct contact with bare copper bus bars and component posts without plastic sleeves.

These ring terminals are manufactured to accept 12–10 gauge wire, providing the right balance of current capacity and ease of crimping for mid-range power applications. The #8 stud hole accommodates standard 1/4-inch fasteners commonly found on battery posts, alternator outputs, and fuse block connections. ALLSTAR PERFORMANCE's design ensures a tight, corrosion-resistant crimp that maintains full conductivity under vibration and thermal cycling—critical factors in high-performance engine compartments or vehicles subjected to repeated heating and cooling cycles. The bare copper construction maximizes surface area contact, reducing voltage drop and heat generation across your electrical distribution network.

These terminals excel in custom fuel system installations, auxiliary battery setups, nitrous oxide bottle grounds, and race-car electrical harnesses where every milliohm of resistance matters. The 20-pack quantity provides enough terminals for a complete main battery run, secondary distribution busses, or multiple vehicle projects. Professional installers and serious builders choose non-insulated ring terminals when aesthetics and serviceability matter equally—the bare copper finish keeps your wiring harness transparent and easy to troubleshoot. Simply strip 3/8 inch of insulation from your 12–10 gauge wire, insert into the terminal barrel, and crimp with a proper crimping tool for a permanent, OEM-grade connection.
