Tohnichi MPCL Marking Torque Wrench

Error-Proofing – Simple and Reliable

For bolted connections where a coloured mark on the bolt head or nut is required to verify proper tightening, the tightening and marking process is still often performed in two steps:

1. Tightening with a torque wrench,
   and
2. subsequent marking with a pen.

The MCSP marking torque wrench from Tohnichi performs both tasks in a single operation: When the preset tightening torque is reached, this click-type torque wrench automatically leaves a colored mark on a corner of the nut or screw head. If the target torque is not reached, no mark is applied. Simple and reliable.

This reliably prevents human error during tightening (“PokaYoke”). No forgotten markings on tightened screws, and no marking without first tightening the screw or nut. It also ensures consistent application of the correct torque.

The three models in this series cover a torque range from 10 to 140 Nm. The special fork-type sockets of the MSH15D series feature a guide groove for the marking pen and are available as standard in fifteen wrench sizes ranging from 10 to 32 mm.

This marking system uses disposable pens, so no ink refills are required. A single marker pen can make approximately 2,000 marks and is very easy to replace. It is suitable for both horizontal and vertical work.

Pre-lock Version

The Pre-Lock type is equipped with internal scale. Allows adjustments of the tightening torque on the tool. The set torque is visible via a small scale window in the handle. Setting torque can be operated by an attached hex key to avoid torque change by human mistake. The torque adjustment hex key is a standard accessory. Suitable for applications with changing torques (service jobs).
