Ingersoll Rand 7RLN3D6 Pneumatic Angle Nutrunner | 3/8" Drive Size | 500 RPM | 265 (in-lbs) Torque

Ingersoll Rand 7RLN3D6 Pneumatic Angle Nutrunner combines a 500 RPM free speed with up to 265 in-lbs of torque. Part of the 7 Series, this air-powered nutrunner features a stall-type drive mechanism, which reaches its torque limit as motor speed decreases under load. Its 3/8-inch square drive accepts compatible fastening sockets, while the right-angle head provides access to bolts and nuts positioned near machinery components and assembly fixtures. Torque output can be controlled through air pressure regulation or operator control, making the tool suitable for soft pull applications where critical torque accuracy is not required.

The 7RLN3D6 features lever-start actuation and a convenient push-button reverse control for changing fastening direction during installation and removal. Its 0.7-inch side-to-center distance provides access to fasteners near adjacent surfaces, while the 11.6-inch overall length and 3.5 lbs tool weight support handling during repetitive assembly operations. The tool also features a 1.5-inch angle head height for evaluating overhead clearance in confined fastening locations. With 27 CFM air consumption, a 1/4-inch NPT air inlet, and a 5/16-inch minimum hose size, this pneumatic nutrunner can be integrated into a properly sized compressed-air assembly system. Its manufacturer-listed 79 dBA sound level provides an additional specification for workstation planning.

Applications:

• Industrial assembly lines: Tightening threaded fasteners in mechanical assemblies where critical torque control is not required.
• Automotive component manufacturing: Installing bolts and nuts on suitable brackets, housings, and subassemblies.
• Machinery assembly: Fastening components around equipment frames and fixtures with restricted access.
• Appliance manufacturing: Performing repetitive nut and bolt installation on mechanical assemblies.
• Production maintenance and rework: Removing, adjusting, and reinstalling fasteners using the push-button reverse function.

FAQs:

• Q: What is the maximum torque of the Ingersoll Rand 7RLN3D6?
  A: The 7RLN3D6 provides up to 265 in-lbs of torque at a free speed of 500 RPM. Torque can be controlled through air pressure regulation or operator control.
• Q: What is a stall-type pneumatic nutrunner?
  A: A stall nutrunner continues driving the fastener until increasing load resistance causes the motor to stall. Unlike an automatic shut-off nutrunner, it does not stop at a calibrated preset torque and is recommended for soft pull applications not requiring critical torque control.
• Q: What socket drive does the 7RLN3D6 use?
  A: This model features a 3/8-inch square drive for compatible fastening sockets. Socket selection should match the fastener dimensions and intended fastening application.
• Q: Can the 7RLN3D6 operate in reverse?
  A: Yes. The tool includes a push-button reverse control that allows operators to change rotation direction for removing or repositioning threaded fasteners.
• Q: What are the compressed-air requirements for the 7RLN3D6?
  A: The manufacturer specifies 27 CFM air consumption, a 1/4-inch NPT air inlet, and a 5/16-inch minimum hose size. The compressed-air supply should be sized to meet these operating requirements.
