⚡ At a Glance
- • Crimp Quality: Secure, consistent crimps across the 0.5–6mm² insulated terminal range
- • Best for: DIY enthusiasts, mechanics and electricians handling vehicle and domestic wiring
- • Not ideal for: Specialist work with uninsulated terminals or uncommon connector formats
Includes a ratchet-style crimper plus 370 terminals covering 0.5–6mm², with colour-coded sizing cues. Hardened alloy steel construction and upgraded square-shaped jaws aim to produce tighter, more reliable crimps.
Secure, slip-free crimps, with exclusive square-shaped jaws
Jaw moulding changed from a common half-arc shape to a square shape to reduce gap error, allowing jaws to sit closer to terminals. The closer fit creates a more even compression profile along the connector barrel.
Tighter mechanical contact lowers the risk of loose connections and slipping wires, improving electrical contact reliability for vehicle and household wiring.
Faster size matching, with colour-coded quick-match cues
Each terminal size is assigned a distinct colour, and matching cues appear on the jaws for direct visual alignment. Colour coding eliminates the need for magnifiers or repeated checks.
Reduce set-up time during multi-connector jobs, making wiring, repairs and installations faster and less fiddly.
Ready-to-use kit, with 370 terminals covering common sizes
The set contains 370 terminals spanning 0.5–6mm², including several connector types such as ring, bullet and spade. Included selection supports multiple gauge ranges listed in the crimping specification.
Suitable for most domestic and vehicle wiring tasks without immediate need to buy additional connectors, ideal for roadside repairs and workshop use.
