Ingersoll Rand 231HA Air Impact Wrench | 1/2" Square Drive | 8000 RPM | 600 (ft-lbs) Max Torque | Trigger Start

For tire changes, vehicle repairs, and facility maintenance involving stubborn fasteners, the Ingersoll Rand 231HA Pistol Grip Air Impact Wrench delivers substantial loosening power in a full-size pneumatic configuration. Featuring a 1/2" square drive and 600 ft-lbs (813 Nm) of maximum reverse torque, this impact wrench helps technicians remove tight nuts and bolts from automotive components, equipment assemblies, and machinery. Its 550 ft-lbs of forward fastening torque provides additional capacity for suitable installation tasks, while the 8,000 RPM free speed (rotational speed without load) supports efficient fastener rundown. The 231HA combines a powerful vane motor, which uses sliding vanes driven by compressed air to produce rotation, with an impact mechanism that delivers repeated rotational blows to the fastener.

The Ingersoll Rand 231HA features a steel hammer case and aluminum housing that help protect internal components during regular workshop use. Its pressure-feed lubrication system supplies grease to the impact mechanism, while variable power control in forward and reverse allows technicians to adjust output for different fastening operations. A contoured pistol grip provides a secure handling surface, and the through-handle exhaust directs discharged air away from the operator. Measuring 7.3" in overall length and weighing 5.8 lbs, this standard-anvil model fits conventional automotive service applications without the additional length of an extended-anvil wrench. The 1/4" NPT air inlet, 3/8" minimum hose size, and 4.2 CFM average air consumption provide important information for matching the wrench to a suitable compressed-air system.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator (FRLs)

Applications:

• Automotive tire and wheel service – Removing compatible wheel nuts and performing routine wheel removal and installation during vehicle maintenance.
• Professional automotive repair – Loosening suspension bolts, mounting fasteners, and other accessible mechanical hardware during vehicle servicing.
• Fleet and light truck maintenance – Servicing appropriately sized threaded fasteners on fleet vehicles, repair equipment, and light trucks.
• Industrial maintenance and MRO – Removing bolts from machinery brackets, equipment housings, and mechanical assemblies during servicing or component replacement.
• Facility and mechanical workshops – Performing general fastening, equipment repair, and mechanical disassembly where a full-size pneumatic impact wrench is appropriate.

FAQs:

• Q: How much torque does the Ingersoll Rand 231HA impact wrench deliver?
  A: Ingersoll Rand specifies 600 ft-lbs of maximum reverse torque and 550 ft-lbs of forward fastening torque. The reverse rating describes the wrench's loosening capability, while the forward rating represents fastening output. Neither figure is a calibrated final tightening setting, so use an appropriate torque wrench when exact tightening torque is required.
• Q: What is the difference between the Ingersoll Rand 231HA and 231HA-2?
  A: The 231HA has a standard-length anvil, measures 7.3" overall, and weighs 5.8 lbs. The 231HA-2 features a 2" extended anvil, measures 9.1" overall, and weighs 6.1 lbs. Both share the manufacturer's 600 ft-lbs maximum reverse torque and 8,000 RPM free speed. Choose the extended-anvil version when additional socket reach is necessary.
• Q: What size air compressor is required for the 231HA?
  A: The wrench has an average air consumption of 4.2 CFM and a reported consumption of 22 CFM at load. It uses a 1/4" NPT air inlet and requires a minimum 3/8" air hose. Size the compressor and air distribution system according to the expected duty cycle, operating pressure, and airflow needed while the tool is working under load.
• Q: How does the Ingersoll Rand 231HA compare with the 231C?
  A: Both models are full-size 1/2" square-drive pneumatic impact wrenches rated at 600 ft-lbs maximum reverse torque and 8,000 RPM free speed. The 231HA uses a steel hammer case and aluminum housing, and Ingersoll Rand lists 550 ft-lbs forward fastening torque for this model. The 231C is a separate configuration with its own published specifications and service requirements.
• Q: Can the Ingersoll Rand 231HA be used for automotive wheel removal?
  A: Yes. Ingersoll Rand identifies vehicle repair and tire work among the applications for the 231HA Series. Use properly fitted impact-rated sockets, and finish tightening wheel fasteners with a calibrated torque wrench according to the vehicle manufacturer's specifications.
