Purpose and user

The Klein Tools SN-06 is a ratchet crimper built for electricians and technicians who work with non-insulated terminals. It handles wire sizes from AWG 20 to 10 and provides a controlled crimp cycle for reliable connections. The tool is suited for panel building, automotive wiring and general electrical maintenance where consistent termination quality matters.

Build integration

The crimper fits into a technician's hand-tool kit and requires no external power or calibration equipment. Its ratchet mechanism forces a full cycle before release, which removes guesswork and frees the user from checking crimp tightness by feel. The non-slip grip and release lever allow repeated use in tight enclosures or awkward angles without hand fatigue.

Upgrade path

This tool replaces basic pliers-style crimpers that rely on operator pressure and often produce loose or damaged terminals. The jump is worth it when a job demands repeatable crimps on non-insulated terminals across the AWG 20-10 range, especially where rework costs or safety standards rule out inconsistent hand pressure.

Questions about this item

What is the smallest wire gauge the Klein Tools SN-06 can crimp without the ratchet slipping?

The tool crimps down to AWG 20 (.5 mm²) non-insulated terminals; the ratchet mechanism forces a full cycle so the jaws cannot release early.

How hot do the handles get during a full day of repetitive crimping?

The non-slip grips stay cool because the ratchet requires only moderate hand force; no external power source generates heat.

Which terminal type must I already have on hand for this crimper to work?

You need non-insulated terminals sized for AWG 20-10 (0.5-6 mm²); insulated or other styles will not fit the jaws.
