## Long description

Insulated copper ring terminals Erko KOE M10 x 35 mm, pack of 50, provide a secure crimp connection for copper conductors where an M10 bolt mounting is required. The terminals combine a copper conductive eye with an insulating sleeve to protect the crimp and reduce the risk of short circuits. They are designed for use in automotive, industrial and general electrical installations for grounding, earthing and power wiring applications where robust mechanical and electrical contact is needed.
Advantages
The insulated copper construction ensures low contact resistance and good corrosion resistance for consistent electrical performance. The integrated insulating sleeve simplifies installation by covering the crimped conductor, improving safety and reducing exposure to accidental contact. The ring shape fits M10 bolts and offers reliable mechanical retention under vibration. Supplied in a pack of 50, these terminals support batch wiring tasks and maintenance jobs.
Suitable for
Automotive wiring and battery grounding
Industrial control panels and machinery connections
Building electrical installations and earthing points
Maintenance, repair and retrofit electrical work
Key specifications
Material: copper conductor with insulating sleeve
Terminal type: ring terminal for bolt mounting
Bolt size compatibility: fits M10 bolts
Overall length (approximate): 35 mm
Pack quantity: 50 pieces
How to use
Strip the conductor insulation to the appropriate length, insert the bare copper conductor fully into the terminal barrel, and crimp using a suitable crimping tool sized for the terminal and conductor cross-section. Once crimped, position the ring over the M10 bolt or stud and secure with the appropriate nut or fastening hardware. Ensure the insulating sleeve covers the crimp area and that the connection is mechanically tight and electrically sound before power is applied.
Usage recommendations
Choose a crimping tool rated for insulated terminals and matched to the conductor cross-section for consistent, reliable crimps. Use appropriate torque values on M10 fasteners to avoid loose connections or damage to the terminal. For outdoor or corrosive environments, consider additional protective measures such as corrosion inhibitors or sealed enclosures.
