GUSTAV KLAUKE GMBH K05 Manual Crimping Pliers 6-50 mm² Hexagonal Crimp Tool

Electricians and maintenance technicians working on power distribution panels or industrial machinery often need a reliable way to attach cable lugs to stranded copper conductors. The GUSTAV KLAUKE K05 manual crimping pliers handle this task with precision for cross-sections from 6 to 50 mm². Its integrated hexagonal dies and self-adjusting ratchet mechanism produce uniform, gas-tight crimps on non-insulated connectors, ensuring low contact resistance and long-term durability.

Key specifications

• Crimping range: 6–50 mm²
• Crimping profile: hexagonal (Sechskant)
• Integrated dies for 6, 10, 16, 25, 35, and 50 mm²
• Self-adjusting ratchet mechanism with emergency release
• Tool length: approx. 390 mm
• Material: high-quality tool steel with ergonomic non-slip handles

Why choose it

The K05 is built for professionals who demand consistent results. The ratchet mechanism ensures full crimp cycles every time, preventing under-crimping, while the emergency release allows you to correct mistakes without damaging the tool or connector. The hexagonal profile is the industry standard for non-insulated lugs, providing excellent mechanical strength and electrical conductivity. Its robust steel construction withstands daily use in demanding environments, from construction sites to marine applications.

Ideal use cases

• Electrical installations in residential and commercial buildings
• Automotive and marine wiring repairs
• Industrial control panel assembly
• Maintenance of power distribution systems

Good to know

The ergonomic handles reduce hand fatigue during repetitive crimping tasks, and the non-slip grip improves safety. While the tool is manual, its optimized leverage design requires less force than standard pliers. Always use the correct die size for the conductor cross-section to achieve a proper crimp. The tool is not intended for insulated terminals or connectors.
