Built for fast, controlled screw installation in repetitive assembly work, the Cleco 8RSA-40BQ push button reverse inline screwdriver delivers a high 3,200 RPM free speed for rapid rundown on smaller fasteners. Its 0.5 - 2 ft-lbs torque range supports low-torque fastening where consistency matters more than high clamp load, while the 1/4" hex quick change drive allows fast bit changes at production stations. The Clecomatic clutch (a mechanical clutch system used to improve torque repeatability at shutoff) helps reduce fastening variation in applications such as electronics, appliances, aerospace subassemblies, and light manufacturing.
The inline push-to-start layout activates the tool when forward pressure is applied, helping operators maintain a steady fastening rhythm without using a separate trigger. Push button reverse allows quick screw removal or correction during rework, inspection, or assembly adjustment. With 19.1 SCFM air consumption, a 1/4" NPT air inlet, and a compact 8.9" length, the 8RSA-40BQ is a practical choice for workstations that need speed, repeatable shutoff, and a compact screwdriver body.

- Push-to-start operation activates the screwdriver through forward pressure, reducing extra hand movement during repetitive work.
- Push button reverse helps operators remove or correct screws without switching tools.
- 1/4" hex quick change drive allows fast bit changes for workstations handling multiple screw types.
- Compact inline body supports bench assembly, fixture work, and access into tighter assembly areas.
- Standard equipment includes operating instructions, service manual, suspension bail, and torque springs required to meet the indicated torque range.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)
Applications:
- Electronics assembly: Driving small screws into covers, housings, brackets, and light component assemblies where fast rundown is useful.
- Appliance production: Installing screws in panels, trim pieces, internal supports, and light mechanical subassemblies.
- Aerospace subassembly: Repetitive low-torque screw installation where inline access and consistent clutch shutoff are important.
- Automotive interior and trim stations: Fastening clips, covers, panels, and light brackets that require controlled pneumatic screwdriving.
- Inspection and rework benches: Removing and reinstalling screws during adjustment, repair, or quality-control checks.
FAQs:
- Q: When should I choose the 8RSA-40BQ instead of a slower 8-Series model?
A: Choose the 8RSA-40BQ when the application uses smaller fasteners and benefits from faster rundown speed. Its 3,200 RPM free speed is faster than the 8RSA-30BQ, 8RSA-20BQ, and 8RSA-10BQ, but its maximum torque is lower at 2 ft-lbs. - Q: What does the “BQ” configuration mean on this model?
A: For this SKU, the drive configuration is a 1/4" hex quick-change drive. This lets operators change compatible screwdriver bits quickly without a separate chuck key. - Q: Is the Cleco 8RSA-40BQ reversible?
A: Yes. The 8RSA-40BQ uses push-button reverse, allowing the operator to back out screws or correct an assembly without reaching for a separate removal tool. - Q: What air supply does this screwdriver require?
A: This tool is rated for 90 PSI operation and lists 19.1 SCFM air consumption, a 1/4" NPT air inlet, and a 3/8" minimum hose I.D. Verify that the workstation can maintain the required air flow during repeated fastening cycles. - Q: Is this the right tool for removing stuck screws or bolts?
A: No. The 8RSA-40BQ is a clutch-controlled assembly screwdriver for repetitive fastening and light rework. For seized screws, bolts, or breakaway work, use a properly selected impact wrench, drill, or removal tool.
