Ensure your electrical connections stay put with our 5.3mm Insulated Red Ring Terminals. Engineered for permanent installations, these connectors are designed to be bolted down, providing a far more secure connection than standard push-on terminals. The 5.3mm ring size is perfectly matched for M5 studs, while the red insulation indicates a precision fit for your small-gauge 22-16 AWG wiring.
Precision M5 Stud Fit: The 5.3mm internal diameter is specifically designed to slide over M5 or #10 size screws and bolts for a snug, professional fit.
Superior Conductivity: Constructed from tin-plated copper to provide maximum electrical flow while remaining highly resistant to corrosion and oxidation.
Rugged Vinyl Insulation: The durable red PVC sleeve protects against short circuits and provides extra strain relief for the wire at the crimp point.
Tapered Wire Entry: Features a flared "Back" design that allows stranded wires to be inserted quickly without stray strands getting caught.
Terminal Type: Ring Tongue / Crimp Lug.
Ring Size: 5.3mm
Insulation Material: High-Flexibility Vinyl (PVC).
Color: Red
Automotive Grounding: Securely ground lights, sensors, and accessories to the vehicle chassis.
Power Distribution: Connect small-gauge wires to bus bars, battery terminals, or solar controllers.
Industrial Equipment: Terminate control wires into screw-type terminal blocks within electrical panels.
Marine Wiring: The tin-plated core makes these ideal for 12V marine electrical systems where moisture is a concern.
Will this fit an M5 bolt?
Yes! The 5.3mm opening is specifically sized to provide a small amount of clearance for a standard M5 or #10 bolt for easy installation.
What is the best way to crimp these?
For a reliable "gas-tight" connection, use a ratcheting crimper designed for insulated terminals. This ensures the barrel is crushed evenly around the wire strands.
Why choose a ring over a spade terminal?
Ring terminals provide 360-degree contact and cannot be pulled off the stud without removing the screw, making them much safer for high-vibration environments.
