Secure your critical wiring with our 6.5mm Insulated Red Ring Terminals. These heavy-duty ring connectors are designed for permanent bolt-on applications, providing a level of security that push-on connectors simply can't match. The 6.5mm internal diameter is optimized for M6 studs and bolts, while the red insulation indicates a precision fit for 22-16 AWG small-gauge wiring, making them a staple for professional automotive and industrial installations.
Precision M6 Stud Compatibility: The 6.5mm ring opening is perfectly sized to fit standard M6 or 1/4" studs and screws without excessive play.
High-Conductivity Copper Core: Features a tin-plated copper body for maximum current flow and long-term protection against harsh environments and corrosion.
Protective Vinyl Insulation: The durable red PVC sleeve provides essential electrical insulation and acts as a robust strain relief to prevent wire fatigue at the crimp joint.
Flared Wire Entry: Designed with a wide "Back" opening to guide stranded 22-16 AWG wires smoothly into the barrel, ensuring no stray strands are left behind.
Terminal Type: Ring Tongue Terminal / Crimp Lug.
Ring Size: 6.5mm
Insulation Material: High-Grade Vinyl (PVC).
Color: Red
Chassis Grounding: The preferred choice for grounding low-current sensors and electronics directly to a vehicle frame or metal enclosure.
Battery Accessories: Ideal for connecting battery chargers, maintainers, or small 12V accessories to standard battery terminal bolts.
Industrial Power Strips: Used for terminating power and ground leads onto high-current bus bars and screw-type terminal blocks.
Marine Systems: The tin-plated core provides necessary resistance to oxidation in humid or salt-air environments.
Why use a ring instead of a fork/spade terminal?
Ring terminals provide a 360-degree connection that cannot be pulled off the stud without completely removing the screw, making them the safest choice for high-vibration areas.
Do I need a specific tool for these?
For a "gas-tight" and permanent electrical bond, you should use a ratcheting crimp tool specifically calibrated for insulated terminals.
Is the insulation heat-resistant?
The PVC insulation is rated for standard operating temperatures up to 105°C (221°F), suitable for most engine bay and industrial environments.
