Built for controlled tightening on medium-to-large fasteners where cordless mobility and connected setup are useful, the Chicago Pneumatic CP8603C PACK 36V 2.5AH Battery Torque Wrench delivers a 51.6 - 240 ft-lbs torque range with ±4% accuracy. Its 3/4" square drive fits industrial socket sets used in maintenance, vehicle service, and assembly work, while the included S-type reaction bar helps brace the tool against a fixed point during torque application.
As the Connected version of the CP8603, this model gives technicians torque setup through the tool's OLED digital screen or through the CPLinQ app for better control of the tightening process. The 36V 2.5Ah lithium-ion battery platform keeps the wrench mobile around service bays, work cells, fleet vehicles, and field equipment without compressed-air setup. With 20 RPM free speed, angle tightening capability, and hard and soft joint capability, the CP8603C supports controlled fastening on rigid metal-to-metal joints as well as assemblies with some compression from washers, spacers, or similar components.

- High precision ±4% torque accuracy helps technicians tighten medium-to-large fasteners within a defined target range.
- Included S-type reaction bar provides a fixed reaction point during controlled torque application.
- Double-trigger starting system includes a second start button for safer, more deliberate activation during tightening.
- Shut-off-current control helps stop the tool when the programmed torque target is reached.
- Automatic release reaction arm helps avoid the tool staying blocked on the application after the tightening cycle.
- CP Care eligible, with calibration available as part of the preventive maintenance package or as a standalone service.
Kit Includes:
- 1 CP8603C dual-trigger battery torque wrench
- 1 S-type reaction bar
- 2 batteries
- 1 battery charger
- 1 charger cable
- 1 plastic case
Applications:
- Fleet and vehicle maintenance - controlled tightening on chassis, suspension, accessory, and service fasteners where repeatability matters.
- Industrial maintenance and MRO - torque-controlled fastening on machinery guards, brackets, frames, fixtures, and plant equipment.
- Bus, trailer, and utility service - cordless 3/4" drive tightening for medium-to-large fasteners around maintenance bays and field vehicles.
- Assembly and repair stations - connected setup control for repeated fastening where a defined torque value is required.
- Field service crews - battery-powered torque work in locations where compressed air is unavailable, inconvenient, or slower to deploy.
FAQs:
- Q: What does the "C" version add on the CP8603C?
A: The "C" version is the Connected model. It allows torque setup through the OLED digital screen or through the CPLinQ app and includes angle tightening capability. - Q: Does the CP8603C PACK include a reaction bar?
A: Yes. This pack includes one S-type reaction bar, which helps brace the wrench during controlled tightening. Always position the reaction bar against a suitable reaction point before operating the tool. - Q: Does this model include Torque Check or counting sequence functions?
A: No. The CP8603C is the Connected version. Counting sequence functions are reserved for CQ and TC versions, and Torque Check functionality is reserved for TC versions. - Q: Does the PACK version include batteries and a charger?
A: Yes. The CP8603C PACK includes the tool, S-type reaction bar, 2 batteries, 1 battery charger, 1 charger cable, and 1 plastic case. - Q: Is the CP8603C an impact wrench?
A: No. This is a battery torque wrench for controlled tightening. It is used when target torque, accuracy, and repeatability matter more than impact-style breakaway force.
