For production fastening tasks involving wood, self-tapping screws, and soft-joint assemblies, the Ingersoll Rand 41SD25LTQ4 Inline Pneumatic Air Screwdriver combines a 2,500 RPM free speed with a 0–45 in-lbs (0–5.1 Nm) torque range for efficient screw installation. As part of the Ingersoll Rand 41 Series, this air-powered screwdriver uses a stall-type direct-drive mechanism that keeps driving until the motor stalls under load, rather than automatically disengaging at a preset torque. This configuration is particularly useful for soft-pull fastening applications where critical torque control is not required. Its 1/4-inch hex quick-change spindle allows convenient screwdriver bit changes, while the inline body supports straightforward tool positioning during repetitive assembly work.
The 41SD25LTQ4 features lever-start actuation, a simple push-button reverse control, and Ingersoll Rand's Skinsulate housing, which provides a comfortable grip and requires less force and pressure during operation. Measuring 8.1 inches in length and weighing approximately 2.1 lbs, this pneumatic screwdriver offers a practical combination of speed and manageable tool dimensions for manufacturing workstations, component assembly, and general production fastening. Its torque output can be influenced by regulating the supplied air pressure, although the stall mechanism is not a substitute for a precision torque-controlled shut-off clutch.

Features:
- Stall-type direct drive mechanism allows the motor to run until it stalls under load, making the tool suitable for soft-pull fastening applications that do not require critical torque control.
- 2,500 RPM free speed supports efficient screw rundown during repetitive assembly operations.
- 0–45 in-lbs torque range accommodates fastening tasks where torque output can be managed through the supplied air pressure and joint characteristics.
- Skinsulate housing provides a comfortable grip surface, requiring less force and pressure during operation.
- Inline configuration supports natural tool alignment with fasteners during straight-access assembly work.
- Lever-start actuation provides convenient control of screwdriver operation.
- Simple push-button reverse allows operators to change rotational direction for screw installation or removal.
- 1/4-inch hex quick-change spindle facilitates convenient changes between compatible screwdriver bits.
Made in USA 
Applications:
- Wood product assembly – driving screws into wood components where fastening resistance changes as the screw seats.
- General manufacturing – repetitive screw installation at production workstations and component assembly benches.
- Self-tapping screw applications – fastening operations where driving torque may exceed final seating torque.
- Light mechanical assembly – installing threaded fasteners in suitable noncritical torque applications.
- Production equipment assembly – screwdriving operations involving soft joints and materials that do not require precision shut-off torque control.
FAQs:
- Q: How does the stall mechanism work on the Ingersoll Rand 41SD25LTQ4?
A: The screwdriver continues rotating until resistance from the fastener causes the air motor to stall. Unlike an automatic shut-off clutch, the stall mechanism does not independently stop the tool at a calibrated torque setting. It is recommended for soft-pull applications that do not require critical torque control. - Q: Can the torque output of this pneumatic screwdriver be adjusted?
A: Torque output can be influenced by limiting or regulating the air pressure supplied to the tool. However, actual fastening torque depends on operating conditions and joint characteristics. For applications requiring verified tightening accuracy, a calibrated torque-control solution should be considered. - Q: What screwdriver bits fit the 41SD25LTQ4?
A: This model features a 1/4-inch hex quick-change spindle for compatible hex-shank screwdriver bits. Select the appropriate bit profile and size for the fastener being installed. - Q: What air supply does the Ingersoll Rand 41SD25LTQ4 require?
A: Manufacturer specifications list air consumption of 20 CFM (565 L/min) and a 1/4-inch NPT air inlet. The compressed-air system should be sized according to the manufacturer's operating pressure and air supply recommendations. - Q: Is this screwdriver suitable for precision torque-controlled assembly?
A: No. This stall-type model is intended for fastening applications where critical torque control is unnecessary. For joints requiring a defined tightening torque and automatic clutch disengagement, consider an appropriate adjustable shut-off clutch screwdriver.
