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

When a standard-length impact wrench cannot reach recessed fasteners, the Ingersoll Rand 231HA-2 Pistol Grip Pneumatic Impact Wrench provides additional socket reach with a 2" extended anvil. Designed for vehicle repair, tire service, facility maintenance, and mechanical equipment servicing, this air-powered wrench features a 1/2" square drive and delivers 600 ft-lbs (813 Nm) of maximum reverse torque for loosening stubborn nuts and bolts. Its separately rated 550 ft-lbs of forward fastening torque provides substantial output for compatible installation tasks, while the 8,000 RPM free speed (drive rotation speed without load) supports efficient fastener rundown. The extended anvil positions the socket farther from the wrench housing, making it useful around recessed wheel assemblies, brackets, and nearby obstructions.

The Ingersoll Rand 231HA-2 combines a powerful vane air motor with a steel hammer case and aluminum housing for repeated fastening operations in demanding workshop environments. Its adjustable power management system allows operators to reduce output in forward or reverse, while variable trigger control provides additional control during fastener engagement. Measuring 9.1" (231 mm) in overall length and weighing 6.1 lbs (2.77 kg), this model offers greater reach than the standard 231HA while retaining the same rated torque and free speed. The tool uses a 1/4" NPT air inlet, requires a 3/8" minimum air hose, and has a manufacturer-listed 4.2 CFM average air consumption. These specifications help technicians evaluate the wrench for their available workspace and compressed-air system.

Features:

• 2" extended square-drive anvil provides additional reach when fastening or loosening nuts and bolts positioned inside recessed assemblies.
• 600 ft-lbs maximum reverse torque supports removal of stubborn automotive and machinery fasteners within the wrench's rated capability.
• 550 ft-lbs forward fastening torque provides the manufacturer's separately specified output for compatible installation operations.
• 8,000 RPM free speed enables quick socket rotation for efficient nut and bolt rundown.
• Powerful vane motor converts compressed air into rotational motion for repeated impact-wrench operation.
• Adjustable power management system permits reduced output in either direction, helping operators adapt the wrench to different fastening tasks.
• Steel hammer case and aluminum housing provide durable metal construction for regular workshop handling and exposure to demanding service conditions.
• Variable trigger operation allows operators to moderate tool output while starting, engaging, or removing fasteners.

Applications:

• Automotive wheel and tire service – Reaching compatible wheel fasteners located deeper inside wheel assemblies or behind surrounding components.
• Vehicle suspension and chassis maintenance – Removing accessible mounting bolts and other mechanical hardware where additional anvil length improves access.
• Fleet and light truck service – Performing fastener removal and installation on appropriate vehicle assemblies during routine maintenance.
• Industrial maintenance and MRO – Accessing recessed nuts and bolts on machinery brackets, equipment housings, and mechanical assemblies.
• Repair and restoration workshops – Disassembling equipment and vehicle components in locations where a standard anvil impact wrench may be obstructed.

FAQs:

• Q: What is the difference between the Ingersoll Rand 231HA and 231HA-2?
  A: The 231HA-2 has a 2" extended anvil, measures 9.1" overall, and weighs 6.1 lbs. The standard 231HA has a standard-length anvil, measures 7.3" overall, and weighs 5.8 lbs. Both models are rated at 600 ft-lbs maximum reverse torque, 550 ft-lbs forward fastening torque, and 8,000 RPM free speed.
• Q: Does the extended anvil make the 231HA-2 more powerful?
  A: No. The longer anvil is an access feature, not a torque upgrade. It allows the socket to reach farther beyond the wrench housing, while the manufacturer specifies the same maximum reverse and forward fastening torque ratings for both 231HA configurations.
• Q: What is the recommended torque range for the 231HA-2?
  A: Ingersoll Rand's product information manual lists recommended ranges of 25–300 ft-lbs in forward and 25–350 ft-lbs in reverse. These are distinct from the higher maximum torque ratings published on the product page. Power regulator settings are not calibrated torque settings, so actual tightening torque should be checked using suitable measurement equipment.
• Q: What compressed-air connection does the Ingersoll Rand 231HA-2 require?
  A: The manufacturer specifies a 1/4" NPT air inlet, a minimum 3/8" internal-diameter hose, and 4.2 CFM average air consumption. The compressor and air distribution system must provide adequate pressure and airflow during actual operation. Average consumption is not the same as instantaneous airflow demand under load.
• Q: Can the 231HA-2 be used for wheel nut removal and installation?
  A: Yes, when the wheel fasteners, socket size, required torque, and available clearance are suitable for the tool. Use properly fitted impact-rated sockets. For final wheel-nut tightening, follow the vehicle manufacturer's torque specification and use a calibrated torque wrench rather than relying on the impact wrench's power regulator.
