Built for controlled socket fastening where clearance is limited, the Cleco 34RAA28AH3 clutch shut-off pneumatic angle nutrunner gives assembly and maintenance teams a 90-degree tool with a 3/8" square drive, 580 RPM free speed, and 10 - 20 ft-lbs torque range. The Clecomatic clutch shut-off mechanism automatically stops the tool when the preset torque is reached, helping improve repeatability on threaded fasteners compared with non-shut-off pneumatic tools that rely only on operator feel.
As part of Cleco’s 34 Series Clecomatic angle nutrunner lineup, the 34RAA28AH3 is suited for moderate-torque fastening on brackets, covers, equipment frames, fixtures, and production assemblies. Its 1.22" head height and 0.57" side-to-center distance help position sockets near edges, housings, and other obstacles, while the lever start gives the operator controlled activation during run-down and final tightening.

Features:
- Clecomatic clutch shut-off supports repeatable torque control by stopping the tool at the adjusted torque setting.
- Angle head configuration helps reach fasteners near housings, rails, brackets, and fixture walls.
- Lever start provides controlled actuation for production fastening and maintenance service work.
- Reversible operation allows the tool to install or remove compatible fasteners within its working range.
- 3/8" square drive accepts matching square-drive sockets for nut and bolt fastening.
- 580 RPM free speed provides controlled run-down for applications that require more torque than faster, lower-torque models.
- Compact head geometry helps improve access when fasteners are close to surrounding components.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)
Applications:
- Manufacturing assembly: Tightening nuts, bolts, and subassembly fasteners where clutch shut-off torque control supports repeatable results.
- Automotive and transportation production: Installing brackets, guards, panels, and mounted components in moderate-torque fastening operations.
- Industrial maintenance and MRO: Servicing machinery, fixtures, conveyors, and equipment frames with controlled pneumatic fastening.
- Aerospace and precision assembly: Reaching fasteners in confined work areas where an angle head improves access and tool positioning.
- Bench and fixture workstations: Repeated socket fastening where speed, access, and preset torque shut-off are all required.
FAQs:
- Q: What type of work is the Cleco 34RAA28AH3 best suited for?
A: It is best suited for controlled fastening within its 10 - 20 ft-lbs torque range. Common uses include production assembly, equipment service, bracket installation, fixture work, and other moderate-torque socket fastening tasks. - Q: What does Clecomatic clutch shut-off do?
A: Clecomatic clutch shut-off stops the tool once the preset torque is reached. This helps reduce over-tightening and supports more consistent fastening from one cycle to the next. - Q: Can this tool replace an impact wrench?
A: No. The 34RAA28AH3 is a controlled-torque nutrunner, not a high-breakaway impact wrench. Use it for repeatable fastening within its rated torque range, not for loosening severely seized bolts. - Q: What sockets are compatible with this nutrunner?
A: This model uses a 3/8" square drive, so it accepts compatible 3/8" drive sockets matched to the fastener size and job requirements. - Q: What air supply information should be checked before installation?
A: Manufacturer data lists a 3/8" NPT air inlet, 5/16" minimum hose I.D., and 34 SCFM air consumption. The air system should be sized to maintain clean, regulated, lubricated air at the tool during operation.
