Ring terminal Erko KCS M10 x 70 mm copper tubular, pack of 20

Ring terminal Erko KCS M10 x 70 mm copper tubular in a pack of 20 is a crimp-style electrical connector intended for creating reliable mechanical and electrical terminations on stranded or solid conductors. The copper tubular construction provides good conductivity and corrosion resistance for grounding, automotive and industrial wiring tasks. The M10 ring bore is sized to fit standard M10 bolts and studs, enabling secure bolted connections in panels, chassis, earthing points and equipment enclosures.

Advantages

The copper tubular design offers consistent contact with conductors after crimping, ensuring low contact resistance and stable current flow. Supplied in a pack of 20, these ring lugs are convenient for bulk installations or repair work. The M10 ring shape provides a secure fit on bolts and studs, reducing the risk of loosening under vibration. The simple crimp termination requires common crimping tools and produces a compact, mechanically robust connection.

Suitable for

• Grounding and earthing connections on electrical panels and equipment
• Automotive battery and chassis connections
• Industrial machinery wiring and control cabinets
• General electrical installations requiring a durable ring lug

Key specifications

• Material: copper tubular construction for good conductivity
• Ring inner diameter: suitable for M10 bolts and studs
• Overall length: 70 mm (body and barrel length combined)
• Termination type: crimp-style barrel for stranded or solid conductors
• Pack quantity: 20 pieces

How to use

Strip the conductor to the appropriate length to fully insert into the tubular barrel, insert the conductor and position the ring terminal so the conductor insulation abuts the barrel lip if applicable. Use a suitable crimping tool matched to the terminal size and conductor cross-section to perform a firm crimp, creating a secure mechanical and electrical joint. After crimping, fit the ring over the M10 bolt or stud and secure with the appropriate washer and nut, ensuring adequate torque for the application and avoiding damage to the terminal.

Usage recommendations

Use terminals of the correct cross-sectional size for the conductor to maintain low resistance and reliable connections. For outdoor or corrosive environments, consider additional corrosion protection such as heat-shrink tubing with adhesive or protective coatings. Inspect crimps visually and, where required, with pull tests to confirm mechanical integrity before energizing circuits.
