Cleco 19RAS06AH3 Pneumatic Stall Collar Reverse Angle Nutrunner | 19 Series | Lever Start | 880 RPM | 4.6 (ft-lbs) Max Torque

When a light assembly station needs more torque from a compact right-angle pneumatic tool, the Cleco 19RAS06AH3 stall collar reverse-angle nutrunner delivers 4.6 ft-lbs / 6.2 Nm of maximum torque for small fasteners that require controlled tightening without moving to a larger tool platform. Its 880 RPM free speed provides steady run-down for production fastening, while the stall design (the air motor stops when joint resistance reaches the tool’s available torque) supports soft-draw applications where the joint compresses as the fastener is tightened.

This 19 Series model uses a 3/8" square drive, making it a practical choice when the application calls for larger sockets than the 1/4" drive versions in the same family. The collar reverse control allows quick directional changes for loosening or rework, and the lever start gives the operator direct control over each fastening cycle. With an 11.0" overall length, 1.19" head height, and 0.50" side-to-center distance, the 19RAS06AH3 is built for fastening around fixtures, brackets, covers, housings, and other areas where a straight tool may not line up with the fastener.

Features:

• Stall fastening configuration supports soft-draw joints where torque rises as the assembly compresses.
• Torque can be adjusted by changing regulated air pressure, helping maintenance and production teams tune output to the joint.
• Compact angle head helps the operator reach fasteners near tooling, flanges, brackets, panels, and inside small assemblies.
• Collar reverse control supports tightening, loosening, and correction work without switching to a separate removal tool.
• Lever start provides direct actuation for repetitive assembly work and short-cycle fastening operations.
• 3/8" square drive accepts compatible 3/8" drive sockets for applications that need more socket capacity than smaller 1/4" drive tools.
• Lightweight 1.3 lb construction helps reduce handling effort during repeated low-torque fastening tasks.
• Standard equipment includes operating instructions, service manual, and suspension bail for workstation use.

Made in USA:

Applications:

• Production assembly cells — fastening small bolts and nuts where the tool must approach the fastener from the side.
• Automotive component assembly — installing hardware on brackets, covers, interior parts, housings, and light mechanical subassemblies.
• Appliance and equipment manufacturing — tightening fasteners inside cabinets, panels, frames, and recessed component areas.
• Industrial electronics and enclosures — controlled low-torque fastening on boxes, access covers, rails, and mounting hardware.
• Repair and rework benches — removing and reinstalling small fasteners during inspection, service, adjustment, and quality checks.

FAQs:

• Q: What makes the 19RAS06AH3 different from the 1/4" drive 19 Series stall models?
  A: The 19RAS06AH3 uses a 3/8" square drive and provides 4.6 ft-lbs / 6.2 Nm maximum torque. It is the better fit when the application needs the highest torque rating in this 19 Series right-angle stall group and uses 3/8" drive sockets.
• Q: How is torque set on this stall nutrunner?
  A: Torque is adjusted by controlling the air pressure supplied to the tool. For consistent assembly results, use a properly regulated air line and verify torque with the quality procedure required for the fastener and joint.
• Q: What does “soft-draw application” mean?
  A: A soft-draw application is a joint that compresses gradually as the fastener tightens, such as assemblies using gaskets, washers, plastics, or layered materials. Stall tools are commonly used in these applications because the torque builds progressively.
• Q: Can this nutrunner remove fasteners as well as tighten them?
  A: Yes. The collar reverse control allows the operator to switch direction for loosening, correction, and rework. It is still a low-torque assembly tool, so it should not be used as a substitute for an impact wrench or high-torque removal tool.
• Q: Is the 19RAS06AH3 suitable for confined spaces?
  A: Yes. The right-angle head, 1.19" head height, and 0.50" side-to-center distance help the tool reach fasteners where an inline or pistol tool may not have enough clearance.
