Effective in preventing human tightening errors (Pokayoke).

When the set torque is reached, the wrench automatically leaves a mark on nuts (bolts) to provide evidence of proper tightening.

Conventionally, the tightening and marking procedure is a two step process: (1) Tighten with a torque wrench; then (2) Make a mark with a pen. Devices in this series prevent a mark from being made if tightening was forgotten.

Evidence that the set torque was reached during tightening remains visible for later work and after your products are shipped to market.

The MCSP series of interchangeable open-end head marking torque wrenches is now on the market.

Simple torque checks and angle checks are possible without removing nutrunners from multi-spindle tightening equipment.

Also useful for rotation angle tightening.

The ST3-BT / ST3-G-BT series of SpinTork torque meters for nutrunners can now also be used in China.

Trusted for facilitating the internetworking of physical devices. The FD / FDD series of click-type preset torque wrenches emit a Click! sound and automatically transmit tightening torque data wirelessly. The series can now also be used in South Korea.

* Even more reliable tightening work is possible with the FDD series, thanks to two rounds of tightening detection functionality.

Upon reaching the set torque, a tightened-to-completion signal is transmitted by radio waves.

The RTDFH / RNTDFH series of cordless Pokayoke (error-proofing) torque screwdrivers emit wireless signals to help prevent human tightening errors, and the series can now also be used in China.

Tohnichi now offers CAD data (2D and 3D) for the QSPCA series of slip-type torque wrenches, which are designed to prevent under- and over-tightening, and for the QSPCAMS / QSPCALS / QSPCAFHS / QSPCAFH series, which are designed to prevent human tightening errors.

Powered by solar energy, so there’s no need to change batteries, saving time and money.

Newly released torque wrenches: the T-BLE/BLQLE for the EU and China, and the T-BLA/QLBLA for the U.S., Canada and Mexico.

When the set torque is reached, the bolt head is automatically marked to indicate tightening is complete. Improvements to the sockets and marker heads of MPQL/MQL and MQSP marking torque wrenches resulted in design changes.

Now popular as IoT devices, Tohnichi’s FD/FDD “Click!” type wireless preset torque wrenches send tightening torque data automatically. The FD/FDD series can now also be used in the EU.

Tohnichi Manufacturing recently released a technical data sheet entitled Torque Wrench Management and Loss Fees. The information is located at the bottom of the LC3/LC3-G Digital Torque Wrench Checker page.

Using an LC3/LC3-G Digital Torque Wrench Checker for daily torque wrench checks could reduce the risk of your delivering products that have quality issues, resulting in lower costs in the long run. The technical data sheet identifies appropriate checking intervals and adjustment limits, taking into account factors such as loss fees, some common lengths of time between checks, cost, and accuracy. Thus, it compares loss under a company’s current circumstances with loss under appropriate conditions.

Now popular as IoT devices, Tohnichi’s FD/FDD “Click!” type wireless preset torque wrenches send tightening torque data automatically. The FD/FDD series can now also be used in China.

Tohnichi Manufacturing will be closed from Friday, April 29 until Thursday, May 5, 2016 for the annual holidays commonly taken in Japan at that time.

Before the holidays, our final day for shipping products is Wednesday, April 27.

Shipping will resume and our offices will reopen to answer inquiries on Friday, May 6.

A click-type wireless data transfer preset type torque wrench, which allows automated wireless tightening torque data transfer at snug torque, "FD/FDD Series" is now available for sale.

Not only the highest workability of easy-to-use click type but the ability of obtaining tightening torque pass/fail judgement on hand promise correct tightening.

Highly reliable tightening work is possible for the FDD series thanks to two rounds of tightening detection function.

Equipped with a brushless motor. Tightening torque accuracy: ±5%. Provides easy access to the Pokayoke system that is designed to prevent human tightening errors. The electric Unitork DU series with torque scale is available in the Japanese market.

Our preset torque wrenches have undergone a model change. The newer versions are presented below.

1) SP/SP2/SP2-MH series open head preset torque wrenches

2) Preset style torque wrench with ring spanner RSP2/RSP2-MH series

3) Preset style torque wrench with spanner for piping SP2-H series

4) Preset style torque wrench with notched open head SP2-N/SP2-N-MH series

5) Preset style torque wrench with wired limited switch for pokayoke SPLS2,RSPLS2,SPLS2-N series

Main improvements

(a) N2 models (SP19N2X10-MH, etc.) have an adjusting tool for QSP3 (Nos. 930 & 931), to facilitate torque adjustments without removing the grip end cap.

(b) The pre-lock mechanism eliminates the need for manual locking.

(No longer necessary to tighten thrust ring bolts after adjusting torque. This reduces workload and boosts reliability.)
