Technical core data at a glance
- For conductor cross-section: 4 mm²
- Screw hole: M8
- Quantity: 25 pieces
- Dimensions (in mm): ØE 8.4 / ØD 4.8 / Ød 3.1 / W 12.5 / B 7.0 / L 23.0 / C1 6.5
Sturdy metal design
The high-quality metal construction ensures a large, uniform contact area. This minimizes contact resistance and safely transmits currents – ideal for DC applications in the 12V and 24V range.
Precisely designed for M8 screw connections
With ØE 8.4 mm, the cable lugs are optimally matched to M8 bolts. The connection sits securely, tightly, and remains reliable even under vibrations or mechanical stress – especially important in vehicles, boats, or off-grid systems.
Clean & permanent crimp connections
The inner guide (Ød 3.1 mm) is optimally adapted to 4 mm² conductors. This allows the cable to be connected quickly, tightly, and permanently. The sturdy tubular shape ensures that the crimp remains mechanically resilient.
