Chicago Pneumatic Electronic Torque Wrench | CP8921 | 20-368 (ft-lbs) Torque Range | 3/4" Square Drive

Built for higher-torque manual tightening and inspection work, the Chicago Pneumatic CP8921 Electronic Torque Wrench gives technicians a digital 20-368 ft-lbs / 25-500 Nm torque range in a 3/4" square drive format. This CP89 eTorque model is suited for larger fasteners where a 1/2" drive torque wrench may not provide enough capacity, including fleet maintenance, heavy vehicle service, industrial MRO, and equipment repair. The digital feedback system helps operators apply torque with clearer confirmation than a mechanical click-style wrench.

The CP8921 is the standalone version, meaning it provides onboard electronic torque measurement without Bluetooth communication, wireless reporting, or angle measurement. Its acoustic buzzer, strong vibration motor, and 12 LED progressive light display help guide the operator as the selected torque value is approached and reached. With ±3% torque accuracy, ISO 6789:2017 compliance, AA battery power, and included calibration documentation, this 3/4" drive wrench is built for controlled manual torque checks on larger service and maintenance fasteners.

• CP89 eTorque electronic torque wrench.
• USB connection cable.
• Calibration certificate.
• Molded plastic case.
• Removable foam insert.

Applications:

• Heavy vehicle service - controlled tightening on trucks, trailers, buses, suspension components, chassis hardware, and service fasteners within the rated range.
• Fleet maintenance - torque checks on larger mechanical assemblies, wheel-end related service work, brackets, frames, and high-load repair components.
• Industrial MRO - manual torque verification on pumps, skids, guards, flanges, machinery frames, and equipment maintenance hardware.
• Equipment repair shops - final torque confirmation on construction equipment, agricultural machinery, and shop-repaired mechanical assemblies.
• Inspection and quality checks - verifying higher-torque fasteners where digital feedback is preferred over a mechanical click-style wrench.

FAQs:

• Q: What torque range does the CP8921 cover?
  A: The CP8921 is listed with a 20-368 ft-lbs / 25-500 Nm customer-facing torque range. The detailed technical data also lists 25 Nm minimum torque and 500 Nm maximum torque.
• Q: Does the CP8921 measure angle?
  A: No. Manufacturer specifications list angle measurement as not available on the CP8921 standalone model. For torque-and-angle measurement and connected reporting, review the CP8921TC Torque Check version.
• Q: What is the difference between CP8921 and CP8921TC?
  A: The CP8921 is the standalone version with digital torque measurement and operator feedback alerts. The CP8921TC is the Torque Check version and adds torque-and-angle functions such as Bluetooth communication, reporting, sequencing, and result management.
• Q: What sockets fit this torque wrench?
  A: The CP8921 uses a 3/4" square drive. Use compatible 3/4" drive sockets and extensions that match the fastener, torque value, and approved work procedure.
• Q: Is the CP8921 an air tool?
  A: No. The CP8921 is an electronic manual torque wrench. AA batteries power the display, feedback alerts, and electronics, while torque is applied manually by the operator.
