Chicago Pneumatic Battery Torque Wrench | CP8603 PACK 36V 2.5AH | 51.6 - 240 (ft-lbs) Torque Range | 3/4" Square Drive

Built for controlled tightening on medium-to-large fasteners without compressed-air setup, the Chicago Pneumatic CP8603 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 fleet, plant maintenance, and equipment service, while the included S-type reaction bar braces the tool against a fixed point to help manage torque reaction during tightening.

This CP8603 is the stand-alone model in the CP86 Series, giving technicians digital torque adjustment directly from the tool's OLED screen without connected reporting requirements. The 36V 2.5Ah lithium-ion battery platform keeps the wrench mobile around service bays, lifts, work cells, and field equipment, while the 20 RPM free speed supports faster rundown than higher-capacity CP86 models. Hard and soft joint capability means the tool can be used on rigid metal-to-metal assemblies as well as joints with some compression from washers, spacers, or similar components.

• Double-trigger starting system includes a second start button for safer, more deliberate activation during tightening.
• Digital OLED screen provides intuitive torque setup and operating feedback directly from the wrench.
• Shut-off-current control helps stop the tool when the programmed torque target is reached.
• 36V 2.5Ah lithium-ion battery platform supports cordless movement around vehicles, equipment, benches, and field work areas.
• CP Care eligible, with calibration available as part of the preventive maintenance package or as a standalone service.

Kit Includes:

• 1 CP8603 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, service, and accessory fasteners where repeatability matters.
• Industrial maintenance and MRO - torque-controlled fastening on machinery guards, brackets, fixtures, frames, 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 - repeatable fastening where a target torque value is required without using a pneumatic setup.
• Field service crews - battery-powered torque work in locations where compressed air is unavailable, inconvenient, or slower to deploy.

FAQs:

• Q: Does the CP8603 PACK include a reaction bar?
  A: Yes. This pack includes one S-type reaction bar, which helps brace the tool during controlled tightening. Always position the reaction bar against a suitable reaction point before operating the wrench.
• Q: What does the stand-alone version mean?
  A: The stand-alone version provides digital torque adjustment at the tool, but it does not include connected CPLinQ reporting, Connected Quality functions, or Torque Check features. Choose C, CQ, or TC versions when connected workflow functions are required.
• Q: Does this pack include batteries and a charger?
  A: Yes. The CP8603 PACK includes the tool, S-type reaction bar, 2 batteries, 1 battery charger, 1 charger cable, and 1 plastic case.
• Q: Is the CP8603 an impact wrench?
  A: No. This is a battery torque wrench for controlled tightening. It is used when target torque and repeatability matter more than impact-style breakaway force.
• Q: What is the difference between torque range and nominal working torque?
  A: The full torque range is 51.6 - 240 ft-lbs, while the nominal working range is 65 - 190 ft-lbs. Use the nominal range for routine tightening selection and the maximum rating only where the application and fastener requirements call for it.
