In modern assembly operations, fastening accuracy, productivity, and operator ergonomics are critical factors in maintaining product quality and manufacturing efficiency. SUMAKE FPB Series Air Shut-Off Screwdriver is designed to provide accurate torque control, consistent fastening performance, and improved operator comfort for a wide range of industrial assembly applications.

Advanced assembly torque solutions 

The FPB Series bridges high torque output with controlled fastening performance. Replacing the conventional MCL cross-switch design, it integrates a patented Tornado Motor architecture, delivering up to 60% higher torque output while reducing reaction torque by 30–40%, improving operator comfort and process stability. This results in stable fastening performance under varying material conditions while maintaining consistent production cycle efficiency.

Unique floating button design  

For operator efficiency and usability, the FPB Series incorporates a patented Reverse Floating Button design, enabling effortless one-hand push-button operation for seamless forward and reverse directional switching, improving fastening workflow efficiency in repetitive assembly tasks. In addition, optimized noise reduction engineering lowers operating noise levels to approximately 67 dB(A), enhancing operator comfort and supporting reduced long-term exposure to industrial noise environments.

Direct-read torque setting scale

For torque control, the FPB Series features a patented Mechanical Torque Value Display (U-Window), enabling direct torque reading and adjustment on the tool for simplified setup and reduced calibration dependency.

With torque repeatability of ±2–3% and compliance with ISO 5393 Class B (±10%) | Cpk ≥ 1.33, the FPB Series ensures repeatable fastening accuracy, reducing process variation and supporting higher consistency in assembly quality and first-pass yield in assembly operations.

An integrated safety cover that prevents unauthorized adjustment while safeguarding the workpiece from cosmetic damage.

Why manufacturers choose this solution for production 

For procurement officers, factory owners and line managers, upgrading to the SUMAKE FPB Series comes down to three high-impact areas:

➡️ Operator Ergonomics: Traditional air tools cause fatigue and repetitive strain injuries (RSI). The patented Tornado Motor and air-floating piston keep button-pressing effort light and comfortable, sustaining peak shift productivity.

➡️ Operational Uptime: Say goodbye to constant downtime. The FPB Series only needs calibration once a year (or every 200,000 cycles). Plus, the mechanical torque indication system slashes setup times.

➡️ Lower TCO (total cost of ownership): Fewer maintenance intervals and zero unplanned downtime drastically cut your total cost of ownership in high-volume environments.
