C.K Tools T3697A Ratchet Crimping Pliers for Uninsulated Terminals 1-10 mm²

Electricians, automotive technicians, and industrial maintenance crews rely on the C.K Tools T3697A when they need secure, repeatable crimps on uninsulated terminals and connectors. From wiring control panels to repairing vehicle harnesses, this ratchet crimping tool handles copper and aluminium conductors from 1.0 to 10.0 mm² (17 to 7 AWG) with consistent, full-cycle compression.

Key specifications

• Crimping capacity: 1.0–10.0 mm² (17–7 AWG)
• Terminal type: uninsulated
• Mechanism: ratchet with adjustable pressure via star wheel
• Quick release for misfeeds or incomplete crimps
• Jaws: high-grade hardened steel, corrosion-resistant finish
• Handles: ergonomic soft-grip
• Overall length: 230 mm

Why choose it

The ratchet mechanism ensures every crimp reaches the correct pressure before the jaws release, eliminating weak or partial connections. The adjustable star wheel lets you fine-tune the crimping force for different terminal materials and sizes, while the quick-release lever allows you to open the jaws mid-cycle if a terminal is misaligned. Hardened steel jaws with a corrosion-resistant coating provide long service life even in demanding workshop environments.

Ideal use cases

• Electrical installations and panel building
• Automotive wiring repairs and custom harnesses
• Industrial maintenance and machinery wiring
• Marine and leisure electrical work

Good to know

The T3697A is a heavy-duty tool intended for professional use. It crimps uninsulated terminals only; for insulated terminals, a different die set or tool is required. The oval/indentation crimping profile produces a strong mechanical and electrical bond on solid or stranded conductors within the specified range.
