Ingersoll Rand 41SC8PSQ4 Inline Pneumatic Screwdriver | 800 RPM | 9.7 - 100 (in-lbs) Torque Range | Adjustable Cushion Clutch

For production fastening tasks that demand higher torque with deliberate, controlled screw rundown, the Ingersoll Rand 41SC8PSQ4 Inline Pneumatic Screwdriver delivers a practical combination of adjustable torque limitation and pressure-activated operation. Part of the 41 Series, this pneumatic assembly screwdriver operates at an 800 RPM free speed and offers a 9.7–100 in-lbs (1.1–11.3 Nm) torque range, making it suitable for securing threaded fasteners in mechanical assemblies, equipment housings, and manufactured components. The adjustable cushion clutch limits torque transmitted to the fastener and helps reduce vibration and torque reaction experienced by the operator. Its push-to-start actuation engages the screwdriver when forward pressure is applied against the screw, allowing operators to initiate fastening without squeezing a separate throttle lever.

The 41SC8PSQ4 uses a 1/4-inch hex quick-change spindle for convenient bit changes and a simple push-button reverse for switching between fastening and removal. Its inline body keeps the screwdriver aligned with the fastener during repetitive assembly, while the Skinsulate housing provides a comfortable gripping surface that requires less gripping force. With an overall length of 10.9 inches and a weight of 3.1 lbs, this model fits production environments where consistent handling and accessible controls are important. Compared with faster 41 Series cushion clutch models, its lower free speed and higher maximum torque make it particularly useful for assembly operations where tightening capability takes priority over rapid rundown.

Applications:

• Mechanical equipment assembly: Tightening threaded fasteners in machinery components, mounting brackets, and equipment housings requiring adjustable torque limitation.
• Industrial production lines: Repeated screw installation at workstations where push-to-start activation supports an efficient fastening sequence.
• Automotive component manufacturing: Assembling suitable mechanical subassemblies, mounting components, and interior equipment with threaded fasteners.
• Appliance and fabricated product manufacturing: Securing covers, panels, brackets, and mechanical parts within the screwdriver's specified torque range.
• Industrial maintenance workshops: Removing and reinstalling compatible machine screws during component servicing, equipment adjustments, and mechanical repairs.

FAQs:

• Q: What is the main difference between the Ingersoll Rand 41SC8PSQ4 and 41SC8LTQ4?

  A: Both models operate at 800 RPM and provide the same published torque range of approximately 10–100 in-lbs. The difference is their starting mechanism. The 41SC8PSQ4 uses push-to-start activation, while the 41SC8LTQ4 operates through a lever throttle. Selection depends on the preferred fastening method and workstation setup.

• Q: When should I choose the 41SC8PSQ4 instead of the 41SC10PSQ4?

  A: Choose the 41SC8PSQ4 when the assembly requires torque approaching 100 in-lbs and an 800 RPM free speed is suitable. The 41SC10PSQ4 operates faster at 1,000 RPM but has a lower maximum published torque of approximately 80 in-lbs. Both models use adjustable cushion clutches and push-to-start actuation.

• Q: Does the cushion clutch provide automatic shut-off at the selected torque?

  A: No. The adjustable cushion clutch limits transmitted torque but does not provide the automatic motor shut-off function of a dedicated shut-off clutch screwdriver. For fastening operations requiring automatic shut-off and more stringent torque process control, consider an appropriate Ingersoll Rand shut-off clutch model.

• Q: How is the tightening torque adjusted on this screwdriver?

  A: The adjustable cushion clutch allows the torque-limiting setting to be changed for different fastening requirements. Follow the manufacturer's adjustment procedure and verify tightening results on the actual joint, because fastener and assembly characteristics can affect the final torque.

• Q: What compressed air requirements should be considered before using the 41SC8PSQ4?

  A: The manufacturer lists 20 CFM air consumption and a 1/4-inch NPT air inlet. Ensure the compressed air system can provide the required airflow at the manufacturer's recommended operating pressure. Use appropriately sized air preparation equipment and account for other pneumatic tools operating on the same supply.
