Ring terminal insulated copper Erko KOE M6 x 16mm, pack of 100

Insulated copper ring terminal Erko KOE M6 x 16mm, pack of 100 is designed for forming secure electrical connections to M6 studs and bolts. The terminal combines a copper conductor for reliable conductivity with a molded insulation sleeve that provides basic strain relief and electrical isolation. Supplied in a pack of 100, these ring terminals are intended for repeated use in wiring installations where a durable, bolted connection is needed.

Advantages

These Erko KOE insulated ring terminals provide a stable electrical contact thanks to the copper conductor and a consistent barrel length for uniform crimping. The molded insulation reduces the risk of accidental short circuits and helps protect the conductor from mechanical stress at the crimp point. Supplied in a bulk pack of 100, they are convenient for project work and maintenance tasks.

Suitable for

• Automotive battery and grounding connections on M6 studs
• Industrial control panels and terminal blocks requiring bolted connections
• General electrical wiring where insulated ring terminals improve safety
• Maintenance and repair kits for machinery and equipment

When it may not be suitable

These insulated ring terminals are intended for use on M6-sized studs or bolts; they will not fit larger or smaller fasteners. They are designed for standard electrical wiring and general-purpose applications and are not intended for use in high-voltage, high-temperature, or specially rated environments unless additional verification of suitability is performed.

Key specifications

• Conductor material: copper
• Ring inner diameter: sized for M6 studs/bolts
• Barrel length: 16 mm
• Insulation: molded sleeve for electrical isolation and strain relief
• Pack quantity: 100 pieces

How to use

Strip the conductor to the appropriate length, insert the bare wire fully into the barrel, and crimp using a suitable hand or hydraulic crimper sized for the terminal and conductor cross-section. Fit the ring over the M6 stud or bolt and secure with the appropriate nut and washer. Ensure crimp quality by checking for a firm mechanical and electrical connection and verify insulation covers the exposed conductor to prevent accidental contacts.

What to consider before purchase

• Confirm compatibility with the stud or bolt size (M6)
• Match the terminal to the conductor cross-section and crimp tool capacity
• Consider environmental factors such as vibration, moisture, and temperature that may affect longevity
• Assess whether insulation type and material meet your safety or regulatory requirements

Usage recommendations

For reliable results, use an appropriately sized crimping tool and inspect each crimp for tightness. Where corrosion resistance is critical, consider additional protective measures such as dielectric grease or appropriate washers. Store the pack in a dry place to prevent contamination before installation.
