Cleco 34RAA68AZ4 Clutch Shut-Off Pneumatic Angle Nutrunner | Lever Start | 255 RPM | 25 - 50 (ft-lbs) Torque Range | 1/2" Drive

Built for controlled fastening where higher socket capacity is required, the Cleco 34RAA68AZ4 clutch shut-off pneumatic angle nutrunner combines a 25 - 50 ft-lbs torque range with a 1/2" square drive for compatible industrial sockets. The right-angle head helps operators reach fasteners near brackets, rails, housings, and fixture edges where inline tools may not align properly.

The Clecomatic clutch shut-off system stops the tool when the preset torque is reached, supporting repeatable tightening on production assembly and maintenance tasks. It's 255 RPM free speed provides controlled rundown for medium-torque joints, while the lever start gives the operator deliberate engagement at the fastener. With a 16.2" overall length, 1.60" head height, and 0.70" side-to-center distance, the 34RAA68AZ4 is suited for assembly stations that need torque control, angle access, and 1/2" drive socket compatibility in the same pneumatic tool.

Features:

• Clecomatic clutch shut-off helps stop the tool at the adjusted torque setting for repeatable fastening on controlled assembly work.
• 1/2" square drive accepts compatible industrial sockets for applications where larger socket drive tooling is preferred.
• Right-angle head improves access to fasteners located close to housings, frames, brackets, and fixture plates.
• Indexable angle head allows the head position to be adjusted for better alignment in changing workstation layouts.
• Lever start supports controlled engagement when positioning the socket and starting the rundown.
• Collar reverse lets the operator change direction for fastener removal, correction, or rework.
• Oil-less blades help reduce oil mist in the work area while supporting pneumatic tool operation.
• Standard equipment includes operating instructions and service manual, suspension bail, and clutch adjustment tool.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)

Applications:

• Production assembly: Tightening medium-torque fasteners on frames, housings, mechanical subassemblies, and fixture-mounted components.
• Automotive and truck manufacturing: Controlled socket fastening in locations where body panels, rails, or brackets restrict straight-tool access.
• Industrial maintenance and MRO: Removing and reinstalling bolts during equipment repair, component replacement, and line changeovers.
• Agricultural and construction equipment assembly: Installing fasteners on guards, supports, brackets, and machine structures that require 1/2" drive sockets.
• Fixture-based work cells: Repetitive fastening where torque shut-off, socket alignment, and angle-head access help maintain assembly consistency.

FAQs:

• Q: What is the main difference between the 34RAA68AZ4 and the 34RAA68AZ3?
  A: The 34RAA68AZ4 uses a 1/2" square drive, while the 34RAA68AZ3 uses a 3/8" square drive. Both share the same listed 25 - 50 ft-lbs torque range and 255 RPM free speed, so drive size is the key selection point.
• Q: What does Clecomatic clutch shut-off do?
  A: Clecomatic clutch shut-off stops the nutrunner when the adjusted torque is reached. This helps improve repeatability on assembly fastening compared with stopping the tool by operator feel alone.
• Q: Is this tool used for loosening stuck bolts?
  A: This is a torque-controlled angle nutrunner, not an impact wrench. It may be used for removal or rework within its capability, but its primary purpose is controlled tightening in the 25 - 50 ft-lbs torque range.
• Q: What sockets fit the 34RAA68AZ4?
  A: This model uses a 1/2" square drive, so it accepts compatible 1/2" drive sockets. The socket size and style should match the fastener, torque requirement, and plant tooling standard.
• Q: What air supply does this Cleco nutrunner require?
  A: The published air consumption is 34 SCFM, with a 3/8" NPT air inlet and 5/16" minimum hose I.D. Use clean, regulated air at the manufacturer-specified pressure and pair the tool with a properly sized FRL.
