Pro-source PRO-SM-43-4001 Air Impact Wrench 1/2 in 500 Ft-lb

Product Description

The PRO-SOURCE PRO-SM-43-4001 is a 1/2 inch drive air impact wrench built for heavy-duty fastening tasks in automotive, mechanical, and industrial service environments. Powered by compressed air, it delivers up to 500 ft-lb of torque through a 1/4 inch inlet connection and consumes 4.7 CFM at operating pressure. The angled handle design positions the tool for work in tight or awkward spaces where a standard inline grip would be difficult to maneuver. At 3.42 pounds, it is light enough for extended use without excessive fatigue. This wrench is installed and operated by automotive technicians, fleet mechanics, and general maintenance professionals.

This impact wrench is suited for residential garage shops, commercial auto service bays, fleet maintenance facilities, and industrial assembly lines. The 1/2 inch drive accepts standard 1/2 inch impact-rated sockets, making it compatible with a wide range of fastener sizes encountered in vehicle suspension work, equipment assembly, and structural fastening. The angled handle configuration is particularly useful for wheel service and undercarriage work where tool angle and clearance matter.

Key Features

• 500 ft-lb maximum torque output for heavy-duty fastening and removal
• 1/2 inch square drive accepts standard impact sockets
• Angled handle design improves access in confined work areas
• 4.7 CFM air consumption compatible with typical shop compressor setups
• Lightweight at 3.42 pounds for reduced operator fatigue during extended use

Compatibility

Designed as a standard 1/2 inch drive pneumatic impact wrench suitable for use with any 1/2 inch drive impact-rated socket set and compatible with shop air supply systems delivering adequate CFM and pressure.

Installation Notes

Installation and operation should be performed by qualified mechanics or technicians familiar with pneumatic tool safety. Before connecting to an air supply, verify the line pressure and CFM output of the compressor meet the tool requirements. Always use impact-rated sockets rated for the torque output of this tool — standard chrome sockets are not rated for impact use and can fracture. Disconnect the air supply before changing sockets or performing any service on the tool.
