Tohnichi MCSP

Capacity 50 / 100 / 140 Nm

Marking Preset Wrench with Spanner Head

The MCSP is a preset type interchangeable open end head marking torque wrench. It automatically marks a corner of the nut (or bolt) on the side, when the set torque is reached. 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. Tohnichi’s MCSP series marking torque wrench prevents a mark from being made if tightening was forgotten.

A preset clicker torque wrench is ideal for successive tightenings at the same torque. The MCSP series torque wrenches come in a selection of three body types, permitting tightening torque applications from 10 to 140 Nm. MSH15D series interchangeable heads for the MCSP series offer a selection of 14 sizes. Interchangeable open end head dimensions (width across flats) of nuts (bolts) are covering 12, 13, 14, 16, 17, 18, 19, 21, 22, 24, 26, 27, 30, and 32 mm.

Uses a disposable marker, so no need for ink refills. One marker performs about 2,000 markings. Marker replacement is easy. MCSP marking wrenches are suitable for horizontal as well as for vertical applications.

* The requirements and testing methods of the DIN EN ISO 6789 are valid for the rated output (capacity) for a measuring range from 20% to 100%.

A torque tool should be selected so that it is mainly used in its medium torque range. If you had to work regularly close to the maximum load capacity, a larger model should be chosen to prevent risk of overtorquing.
