Terminal ring copper tubular Erko KCS M10 x 240 mm, pack of 10

The Erko copper tubular ring terminal KCS M10 x 240 mm in a pack of 10 is a crimp or solder terminal designed for creating durable electrical connections to M10 studs. The terminal features a tubular copper barrel that accepts stripped cable conductors and a flat ring end sized to fit M10 bolts and studs. Supplied as a set of ten identical terminals, this product is intended for installations that require reliable metallic contact, good electrical conductivity and resistance to corrosion in industrial, automotive and power distribution applications.

Advantages

These Erko copper tubular ring terminals provide stable electrical contact through a solid copper construction that ensures low contact resistance. Their tubular barrels allow secure crimping or optional soldering of conductors, resulting in robust mechanical retention and improved conductivity. The ring end is formed to match M10 fasteners for consistent fit and clamping force. Supplied in a pack of 10, the terminals offer repeatable connector quality for multiple connection points.

Suitable for

• Industrial switchgear and control panels where M10 stud connections are used
• Automotive and heavy-duty vehicle battery and grounding connections
• Power distribution blocks and busbar terminations
• Grounding and earthing systems requiring corrosion-resistant copper contacts

Key specifications

• Material: copper (tubular construction)
• Ring size: suitable for M10 studs/bolts
• Overall length: 240 mm
• Connection method: crimpable barrel; can be soldered
• Pack quantity: 10 terminals

How to use

Prepare the cable by stripping the insulation to expose the conductor to the appropriate length for insertion into the tubular barrel. Insert the conductor fully into the barrel and perform a crimp using a suitable crimping tool sized for the barrel diameter and conductor cross section. If soldering is preferred, apply solder to the crimped barrel following standard soldering practice to avoid cold joints. Position the ring over the M10 stud or bolt and secure with the appropriate nut and washer, ensuring a tight mechanical and electrical connection. Verify continuity and mechanical retention after installation.

Usage recommendations

Use appropriate personal protective equipment and follow local electrical codes when installing these terminals. Match conductor cross-section to the tubular barrel size and verify compatibility with the crimping tool. For critical or high-current connections consider testing contact resistance and applying anti-corrosion measures if exposed to aggressive environments.
