Cleco 19SCA04Q Collar Reverse Inline Pneumatic Screwdriver | 19 Series | 1,100 RPM | 0.33 - 3.3 (ft-lbs) Torque Range | 1/4" Hex Quick Change Drive

When repeatable fastening control matters on light- to medium-duty assemblies, the Cleco 19SCA04Q inline pneumatic screwdriver gives operators a compact, production-focused tool with a 1/4" hex quick change drive, 1,100 RPM free speed, and 10–40 in.-lbs. torque range for controlled screw run-down on metal, plastic, appliance, electronics, aerospace, and general assembly work. Its Clecomatic clutch (an automatic shut-off clutch that stops the tool at the preset torque) helps reduce over-tightening while maintaining repeatable fastening results across high-volume stations.

The collar reverse configuration allows directional change at the tool body, while the lever push-to-start action gives operators controlled activation during assembly. A lightweight 1.5 lb body and 9.8" overall length make the 19SCA04Q practical for bench work, fixture-adjacent fastening, and repetitive screwdriving tasks where torque consistency and bit access matter more than raw speed.

Features:

• Durable Clecomatic clutch supports repeatable torque control and long calibration intervals in production fastening environments.
• Automatic shut-off clutch stops the tool at the preset torque to help reduce fastener damage and improve assembly consistency.
• 1/4" hex quick-change drive allows fast bit changes for common screwdriver bits used in assembly stations.
• Lever push-to-start operation gives the user controlled activation while positioning the bit on the fastener.
• The collar reverse configuration provides directional control directly at the tool body for assembly and fastener removal tasks.
• Grip material is tested to withstand a range of industrial chemicals commonly found in production and maintenance areas.
• Standard equipment includes operating instructions and service manual, suspension bail, all torque springs required to meet the indicated torque, and lever-only conversion kit 301409.

Applications:

• Electronics and appliance assembly — installing small screws into housings, brackets, covers, and light-duty assemblies where repeatable torque matters.
• Automotive and transportation assembly — fastening interior components, trim hardware, electrical brackets, and small subassemblies on bench or line stations.
• Aerospace and precision manufacturing — controlled screwdriving on light assembly work where consistent torque and reduced over-tightening are important.
• General production fastening — repetitive screw run-down in fixtures, cells, and assembly benches using standard 1/4" hex insert bits.
• Maintenance and tool crib support — replacing older Cleco 5 or 14 Series inline screwdriver configurations in plants standardizing around the 19 Series platform.

FAQs:

• Q: What type of bit does the Cleco 19SCA04Q accept?
  A: This model uses a 1/4" hex quick-change drive, which is made for compatible 1/4" hex screwdriver bits. Always match the bit style and length to the fastener and application.
• Q: What does Clecomatic clutch mean?
  A: Clecomatic is Cleco’s automatic shut-off clutch. Once the preset torque is reached, the clutch shuts off the tool to help maintain repeatable torque and reduce the chance of over-tightening.
• Q: Is this a push-to-start or lever-start screwdriver?
  A: The 19SCA04Q is a lever, push-to-start model. It also includes the manufacturer’s kit to convert the tool to lever-only operation when that setup is preferred.
• Q: What air supply is required?
  A: Cleco rates the tool at 90 PSI / 620 kPa for maximum rated torque. The catalog lists 11 SCFM air consumption, a 1/8" NPT air inlet, and a 3/16" minimum hose I.D.
• Q: Can this be used for high-torque bolting?
  A: No. This is a precision pneumatic screwdriver for low-torque fastening in the 10–40 in.-lbs. range. For higher torque bolts, use a properly rated nutrunner, impact wrench, or torque-controlled fastening tool.
