Ingersoll Rand 41SC8LTQ4 Inline Pneumatic Screwdriver | 800 RPM | 9.7 - 100 (in-lbs) Torque Range | Adjustable Cushion Clutch

For assembly operations requiring higher tightening torque without excessive rundown speed, the Ingersoll Rand 41SC8LTQ4 Inline Pneumatic Screwdriver provides controlled fastening for repetitive production work. Part of the 41 Series, this air-powered screwdriver delivers an 800 RPM free speed and an adjustable 9.7–100 in-lbs (1.1–11.3 Nm) torque range, making it suitable for installing threaded fasteners in equipment housings, mechanical assemblies, and manufactured components. Its adjustable cushion clutch limits transmitted torque as the fastener reaches its set tightening level, helping reduce torque reaction and vibration experienced by the operator. Compared with higher-speed models in the series, the 41SC8LTQ4 provides a broader upper torque range for fastening applications requiring greater tightening capability.

The 41SC8LTQ4 combines an inline body configuration with lever-throttle actuation, allowing operators to maintain direct alignment with the fastener while controlling tool startup. A 1/4-inch hex quick-change spindle simplifies bit replacement, while the push-button reverse provides convenient directional control for fastening and removal. Its Skinsulate housing creates a comfortable gripping surface that requires less gripping force during repeated operation. Weighing 3.1 lbs and measuring 10.9 inches in length, this pneumatic screwdriver is well suited to production workstations where torque control, dependable operation, and practical handling are essential. The 41 Series has also been tested to one million cycles without failure, demonstrating its suitability for repeated assembly operations.

Applications:

• Industrial production assembly: Tightening threaded fasteners in repeated assembly cycles where adjustable torque limitation is required.
• Automotive component manufacturing: Installing screws in brackets, interior assemblies, and mechanical components within the tool's torque capacity.
• Appliance and equipment assembly: Fastening covers, structural panels, mounting components, and equipment housings.
• Mechanical and fabricated product assembly: Driving machine screws and other compatible threaded fasteners in manufactured products.
• Industrial maintenance and repair: Reinstalling suitable fasteners during machine servicing, component replacement, and workshop repairs.

FAQs:

• Q: What makes the Ingersoll Rand 41SC8LTQ4 different from the 41SC17LTQ4?

  A: The 41SC8LTQ4 operates at 800 RPM and provides a torque range extending to 100 in-lbs, while the 41SC17LTQ4 runs at 1,700 RPM with a maximum torque rating of approximately 60 in-lbs. The 41SC8LTQ4 is the better choice when higher tightening torque is required, while the 41SC17LTQ4 offers faster fastener rundown for lower-torque applications.

• Q: How does the adjustable cushion clutch control screw tightening?

  A: The cushion clutch limits the torque transmitted to the fastener at the selected adjustment. It helps reduce torque reaction during operation but does not provide the same automatic shut-off functionality as a dedicated shut-off clutch screwdriver. Final tightening results depend on the fastener, joint characteristics, and clutch setting.

• Q: Can the torque setting be changed for different screws?

  A: Yes. The screwdriver features an adjustable cushion clutch that allows the tightening torque to be changed within its supported range. The selected setting should be verified against the fastening requirements using an appropriate torque measurement method.

• Q: What air compressor requirements should be considered for the 41SC8LTQ4?

  A: The tool has a listed air consumption of 20 CFM and uses a 1/4-inch NPT air inlet. Select a compressed air supply capable of meeting the tool's airflow and recommended operating pressure requirements, particularly during repeated production cycles.

• Q: Is this screwdriver suitable for general workshop use?

  A: Yes, when the application calls for compatible threaded fasteners within the tool's torque range. However, its inline configuration and adjustable cushion clutch are particularly useful for repetitive assembly operations rather than breaking loose seized bolts or performing high-torque automotive repair.
