The PRO-SOURCE Pro-SM-45-4154P is a 3/4 inch drive pneumatic impact wrench built for high-torque fastener work in automotive, heavy equipment, and industrial maintenance applications. It delivers a torque range of 200 to 1,200 ft/lb and a free speed of 5,500 RPM, making it suitable for lug nuts, suspension components, heavy bolts, and structural fasteners. The pistol-grip handle with handle exhaust keeps exhaust air directed away from the operator. At 7.62 pounds, the tool balances output and manageability for extended use.

Typical use cases include truck and fleet maintenance, heavy equipment repair, agricultural machinery service, and structural steel work. The 950 impacts per minute rating supports consistent fastener driving and removal across a range of bolt sizes. It is intended for use by mechanics, millwrights, and other trade professionals working with air-powered tools in high-demand settings.
