For controlled fastening in compact assembly spaces, the Cleco 19RAA12AH3 pneumatic collar reversible angle nutrunner gives operators a right-angle tool with shut-off torque control for repeatable production work. The 3/8" square drive accepts compatible socket tooling, while the 200 RPM free speed supports slower, more deliberate rundown than higher-speed models in the same 19 Series family. Its CLECOmatic clutch shut-off stops the tool when the preset torque is reached, helping reduce over-tightening and improving consistency from fastener to fastener.
This 19 Series lever-start nutrunner is suited to light assembly, rework, and station-based fastening where access and torque repeatability matter more than raw speed. With a listed 1.8 - 8.3 ft-lbs torque range, the 19RAA12AH3 fits small fasteners on brackets, housings, covers, panels, and mechanical subassemblies. Collar reverse allows the operator to back out fasteners without changing tools, making it practical for adjustment and repair tasks on the same assembly line.

Features:
- CLECOmatic clutch shut-off stops the tool when the preset torque is reached, helping support consistent fastening across repeated assembly cycles.
- 200 RPM free speed gives the operator added control during lower-speed rundown on small fasteners and sensitive assemblies.
- Right-angle head helps reach fasteners near fixture walls, brackets, ribs, and other areas where inline or pistol tools may not fit.
- Collar reverse provides quick direction change for fastener removal, correction, or rework without changing tools.
- Lever start supports deliberate tool activation during repetitive bench, fixture, or line-side fastening tasks.
- 3/8" square drive works with compatible sockets for nut and bolt assembly applications.
- Compact 0.50" side-to-center distance helps position the socket close to adjacent components or assembly tooling.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)
Applications:
- Light production assembly — tightening small nuts and bolts where shut-off torque control is required.
- Automotive and transportation components — fastening covers, brackets, panels, and light mechanical subassemblies.
- Appliance and equipment manufacturing — controlled assembly work on housings, frames, guards, and access plates.
- Industrial MRO and repair benches — removing and reinstalling fasteners during inspection, adjustment, and service work.
- Fixture-based assembly stations — reaching fasteners located near clamps, tooling, ribs, and other access restrictions.
FAQs:
- Q: What does the CLECOmatic clutch shut-off do?
A: The CLECOmatic clutch shuts the tool off when the preset torque is reached. This helps improve torque repeatability compared with non-shut-off tools that depend more on operator feel. - Q: Why choose the 200 RPM version instead of a faster model?
A: The 200 RPM speed gives more controlled rundown on smaller or more sensitive assemblies. It is useful when the job benefits from precision and pace control rather than maximum cycle speed. - Q: What sockets does the 19RAA12AH3 use?
A: This model has a 3/8" square drive, so it accepts compatible 3/8" drive sockets matched to the fastener size and application. - Q: Can this nutrunner remove stuck or rusted bolts?
A: No. This is a controlled assembly nutrunner, not an impact wrench. It is intended for fastening and light removal or rework within its rated torque range. - Q: What does collar reversible mean?
A: Collar reversible means the operator changes direction using a collar on the tool. This allows forward fastening and reverse removal without switching to a separate tool.
