Blade Terminal Female Non-Insulated 12-10 20pk

The Blade Terminal Female Non-Insulated 12-10 20pk by ALLSTAR PERFORMANCE is an essential electrical connector set for automotive wiring harnesses, engine bay installations, and custom vehicle builds. As a mechanic, you'll recognize these as fundamental components for secure, low-resistance connections in charging systems, fuel pump circuits, starter motor feeds, and auxiliary lighting projects. Non-insulated blade terminals demand proper crimping and heat-shrink or loom protection, making them the choice of professionals who prioritize reliability and current capacity over quick assembly.

Each terminal in this 20-pack accommodates 12–10 AWG wire gauges, delivering a secure, solder-free crimp connection that resists vibration and thermal cycling under the hood. The female blade design mates with standard 0.187-inch (3/16-inch) male tabs found on relays, fuse blocks, alternators, and aftermarket electrical components. Manufacturing to ALLSTAR PERFORMANCE standards ensures consistent material hardness, electrical conductivity, and dimensional accuracy—critical when working at amperage levels where loose connections generate heat and voltage drop. Proper crimping with a quality terminal tool and immediate heat-shrink protection will prevent corrosion and maintain the integrity of your electrical system for years of service.

Restorers, hot rodders, and EFI tuners benefit most from keeping a 20-pack on hand for fuel system upgrades, main battery runs, and relay panel fabrication. Whether you're wiring a custom engine bay, installing a new alternator, or building a standalone fuel pump controller, these non-insulated female blade terminals deliver the current-carrying capacity and durability that modern automotive electrical demands. Use a crimper rated for 12–10 AWG terminals, test continuity after installation, and always cover with adhesive heat-shrink tubing to prevent accidental shorts and environmental contamination.
