280PCS Car Copper Lug Ring Terminals Cable Electrical Wire Crimp Connectors Kit

This 280-piece copper lug ring terminal kit is a comprehensive, cost-effective solution for secure electrical wire connections in automotive, marine, and household wiring projects. Packed with a variety of ring terminal sizes, it caters to different wire gauges and bolt diameters, making it a go-to choice for both professional mechanics and DIY enthusiasts.

Each terminal is crafted from high-purity copper, ensuring excellent electrical conductivity and minimal power loss during current transmission. The copper surface is plated with anti-corrosion tin, which shields against rust, oxidation, and battery acid damagecritical for long-term use in under-hood or marine environments. The kit includes multiple ring sizes to fit common bolt diameters and wire gauges, with each terminal featuring a closed-end design that prevents wire strands from fraying after crimping. The seamless barrel of each lug is thickened for a tight, stable crimp when paired with standard crimping tools, eliminating the risk of loose connections or voltage drops.

These copper ring terminals are compatible with most solid and stranded copper wires of common automotive gauges, suitable for 12V/24V DC electrical systems. They work seamlessly with bolts of various diameters, making them ideal for connecting wires to battery posts, grounding points, terminal blocks, and circuit breakers in cars, trucks, boats, RVs, and household appliances. No soldering is requiredjust crimp firmly for a permanent, reliable connection.

1. Automotive Wiring Projects: Use for battery cable connections, grounding wires, audio system installations, or LED light upgrades, ensuring stable power flow even under vehicle vibration.
2. Marine & RV Maintenance: Perfect for boat wiring (bilge pumps, navigation lights) and RV electrical setups (solar panels, power outlets), as the tin-plated copper resists saltwater corrosion and dampness.
3. Household & Workshop Repairs: Ideal for connecting heavy-duty appliances, power tools, or generator wires to terminal blocks, providing a safe, organized wiring solution.
4. Industrial Equipment Modifications: Suitable for wiring control panels, motors, and machinery, where high-conductivity, corrosion-resistant terminals are essential for consistent performance.

Made with thick, high-purity copper and a uniform tin plating, these terminals resist bending, cracking, and wear even under high torque. The closed-end design prevents moisture and debris from entering the crimped area, reducing the risk of short circuits and extending the lifespan of your wiring. The 280-pack comes in a sturdy, compartmentalized storage case that keeps terminals sorted by size, making it easy to find the right lug for any project without clutter. Each terminal is precision-molded to strict standards, ensuring consistent quality across the entire kit.
