Built for controlled fastening where access is limited and torque repeatability matters, the Cleco CLBA403 CellClutch Cordless Electric Nutrunner delivers a 11.1-30.2 ft-lbs torque range through a 3/8" square drive right-angle head. Its 19-190 RPM speed range gives assembly teams a slower, more controlled rundown than lower-torque models, making it well-suited for medium-torque bolts, brackets, covers, and subassemblies. CellClutch technology combines mechanical clutch fastening with programmable rundown control, helping replace hose-fed pneumatic clutch tools in workstations where cordless mobility and fastening consistency are priorities.
The CLBA403 is part of Cleco’s CellClutch cordless platform, using programmable speed settings, batch-count support, and visual fastening feedback to help operators confirm each joint. The right-angle configuration allows the tool to approach fasteners from the side, while the 18.5 mm side-to-center distance helps the head fit near walls, housings, frames, and other obstructions. At 4.0 lb without battery, this model provides the added torque capacity of a 41 Nm angle nutrunner while staying practical for repeated production use.
Please note that this listing is for the tool only; the Cordless Battery and Charger are not included and must be purchased separately.

Applications:
- Production assembly: Controlled tightening of medium-torque fasteners where repeatability and visual feedback are important.
- Automotive and transportation manufacturing: Fastening brackets, covers, guards, and frame-mounted components in confined areas.
- Heavy equipment and machinery assembly: Running down bolts on housings, panels, and subassemblies that require a right-angle approach.
- Appliance and equipment production: Repeated fastening into fixtures or assemblies where clutch shut-off is preferred over impact force.
- Maintenance and MRO benches: Controlled bolt tightening during component repair, fixture work, and small-batch assembly.
FAQs:
- Q: What is the CLBA403 used for?
A: The CLBA403 is used for controlled tightening of bolts and nuts within its 11.1-30.2 ft-lbs torque range. It is best suited for assembly and production fastening where repeatable torque shut-off is more important than breakaway power. - Q: Is this the same type of tool as an impact wrench?
A: No. This is a clutch-controlled cordless nutrunner, which means it is built for controlled fastening. Impact wrenches are better for loosening stuck fasteners, while this tool is better for tightening fasteners to a repeatable torque target. - Q: Why choose the CLBA403 instead of the CLBA303?
A: The CLBA403 provides a higher torque range of 11.1-30.2 ft-lbs compared with the CLBA303’s 6.1-22.1 ft-lbs range. Choose the CLBA403 when the joint requires more torque and the slower 190 RPM top speed fits the fastening process. - Q: What does the right-angle head help with?
A: The right-angle head lets the drive reach fasteners from the side. This helps when working near housings, frames, panels, brackets, or other obstructions where a pistol tool or inline tool cannot approach the fastener straight on. - Q: Does this SKU include the battery and charger?
A: The provided product data does not confirm battery or charger inclusion. Verify kit contents before ordering, especially if the tool must arrive ready to run in a new CellClutch workstation.
