24-12 AWG Ratcheting Crimper

The Klein Tools crimping tool handles insulated and non-insulated terminals from 24 to 12 AWG. Its ratcheting mechanism multiplies hand force for consistent, repeatable crimps. Clear metric and AWG markings on the jaws speed up size selection. The compact frame weighs 0.77 lbs and fits in a standard tool pouch.

Capacity and headroom

Five jaw slots cover the full 24-12 AWG range so one tool replaces several single-size crimpers. The star-wheel pressure dial lets you fine-tune force for each terminal type, preventing under- or over-crimping. A one-touch quick release clears jams instantly. Hardened jaws rated at 45 HRC resist wear during high-volume work.

Adjustable pressure star wheel

The star wheel is the single spec that decides fit: it sets exact crimp height for every terminal in the 24-12 AWG window. Turn the dial to match the terminal barrel, ratchet until the handle releases, then press the quick-release lever. No other adjustment is required. Not for buyers who need crimping outside the 24-12 AWG range or who require a powered crimp cycle.

Questions about this item

Will this 24-12 AWG ratcheting crimper work with the older non-ratcheting terminals I already have in stock?

The tool covers 24 to 12 AWG and includes multiple jaw slots, so it can crimp a wide range of terminal sizes you may already keep.

How can I verify the 45 HRC jaws are delivering consistent pressure after I set the star wheel?

The ratchet mechanism only releases once the preset pressure is reached, giving a tactile click that confirms each crimp meets the adjusted setting.

Does the kit include any terminals or just the 0.77 lb crimper with its quick-release and adjustable star wheel?

Only the crimping tool itself is supplied; terminals, connectors and wire must be purchased separately.
