Key Advantages Over Traditional Wire Nuts

🔸 Faster Installation – No pre-twisting or tools required; screw-on design cuts labor time by 50%.
🔸 Superior Grip – Zinc-plated spring bites into strands for anti-vibration security.
🔸 Reusable – Unscrew to modify connections without damaging wires (unlike crimp connectors).
🔸 All-Environment Use – Resists moisture, heat, and chemicals in industrial/outdoor settings.

Common Applications

🏭 Industrial – Control panels, motor wiring, and machinery circuits.
🏠 Residential – Light fixtures, outlet junctions, and ceiling fan installations.
🔌 Low-Voltage Systems – Security alarms, HVAC controls, and automotive wiring.
⚡ Renewable Energy – Solar panel arrays and wind turbine connections.

How to Use Screw-On Wire Connectors?

1️⃣ Strip Wires – Remove 10-12mm insulation from each conductor.
2️⃣ Insert & Align – Push wires fully into the connector until flush with the base.
3️⃣ Screw Tight – Rotate clockwise until firm resistance is felt (≈3 turns).
