Product Description
Error-proofing (Pokayoke) Torque Driver MNTD
Application- Torque control for bolts and screws
- Prevents human tightening errors (Pokayoke)
Features
- Determines whether tightening has been missed, by detecting the presence or absence of tightened-to-completion marks. This prevents human tightening errors. (* Patent pending)
- It is common to use a pen to mark work after tightening with a torque screwdriver, but with a Tohnichi marking tool the two actions are combined into one, improving productivity.
- When set torque is achieved, marking is done automatically, eliminating the possibility of an operator otherwise forgetting to mark work.
- Clearly identifiable marks provide evidence of tightening to the required torque, and this evidence remains even after manufacturing and shipping.
- One marker (sold separately) can mark about 1,000 times. Selection of two colors: red and blue.
- Marker positioning is adjustable to accommodate a wide variety of bolts and screws. (* For further details, refer to the PDF catalog.)
- Lineup includes a total of 7 types of Phillips (+) and hex bits for MNTD series products. (Sold separately)
- A non-rotary slip (click type) torque screwdriver. It is the same as models in the LTD/NTD series that create negligible jolting during tightened-to-completion rotary slip.
- Markings on bolt and screw heads can be detected in image form using an industrial level CCD camera, permitting unmanned inspections.

Notes
Note 1: Special bits and markers are required during use. Select the body, special bits and marker that suit your purposes, then place your order.
Note 2: Use screws and bolts with head diameters of at least 5.5 mm.
Note 3: Cannot mark locking bolts or screws with hex holes.
Note 4: Black screws and bolts may reduce mark visibility. If you consider adopting this system, we recommend that you first conduct tests.
Standard accessory
Auxiliary handle (standard accessory only for the MNTD500CN), resin grip (green; standard accessory only for the MNTD120CN and MNTD 260CN).
Engineered Error-Proofing for Quality Assurance
The Pokayoke Torque Driver employs a unique mechanical design to prevent over- or under-tightening, ensuring assembly accuracy in critical applications. Its integrated torque indicator and preset locking mechanism allow only authorized adjustments, addressing quality concerns and minimizing human error. The devices audible click signals users when the set torque is reached, further reducing the chance of assembly mistakes.
Ergonomics and Durability in Demanding Environments
Designed for intensive use, this torque driver features an ergonomic handle for comfortable, prolonged operation and an anti-roll cylindrical shape for added safety on busy production lines. Constructed with high-grade steel, it resists corrosion and stands up to high tensile strengths, making it ideal for challenging industrial scenarios while maintaining consistent calibration.
FAQs of Error-proofing (Pokayoke) Torque Driver:
Q: How does the Pokayoke Torque Driver prevent assembly errors?
A: The driver employs a preset torque limit and an error-proofing mechanical design, producing an audible click when the correct torque (within 0.86 Nm range) is achieved. Its tamper-proof adjustment and locking mechanism ensure only authorized personnel can change settings, minimizing the risk of incorrect tightening.Q: What are the main applications for this torque driver?
A: This tool is widely used in electronics assembly, automotive manufacturing, and industrial production lines where precise torque is critical to ensure safety and product integrity.Q: When should the torque driver be recalibrated?
A: Although the torque driver is factory calibrated and comes with a certificate, regular calibration (typically annually or after extensive use) is recommended to maintain accuracyespecially in high-volume production settings.Q: Where can I use the torque driver safely and effectively?
A: The tool is suitable for use in environments with temperatures between 0C and 50C. Its durable, corrosion-resistant build and ergonomic, non-slip grip make it effective both at assembly workstations and on industrial production lines.Q: What is the process for setting the torque value and ensuring it remains tamper-proof?
A: Torque values are preset by authorized personnel using the built-in locking mechanism. The tamper-proof adjustment system ensures that settings remain secure, and any changes require the proper tool or access.Q: How do users benefit from the integrated torque indicator gauge?
A: The integrated torque indicator provides clear, immediate feedbackpaired with an audible clickat the preset torque value, reducing guesswork and helping operators consistently achieve proper tightening.Tell us about your requirement
