Drehmomentschlüssel 5–25 Nm 1/4", Koffer ITW525 – Stix

Precise tightening of small fasteners

The torque wrench ITW 525 is designed for controlled tightening of bolts and nuts to a specified torque. The range of 5–25 Nm makes this model particularly suitable for tasks requiring relatively low and precisely set tightening torques.

It can be used in automotive and motorcycle workshops, service centers, and for work in a home garage – wherever the vehicle or component manufacturer specifies a required torque within the wrench’s operating range.

Clear torque adjustment

The ITW 525 has a mechanical scale that allows precise setting of the torque value. Adjustment is made by rotating the handle after first releasing the locking mechanism. Once the required value has been set, the lock prevents the handle from accidentally changing the setting during use.

The wrench features a torque scale in the following units:

• Nm (N·m)
• kgf·m

Accuracy ±3%

The wrench mechanism allows the required torque to be set with an accuracy of ±3%. Once the preset value is reached, the mechanism signals it with a characteristic “click” and a noticeable release, indicating that tightening should be stopped.

1/4" ratchet with 42 teeth

The wrench is equipped with a 1/4" square drive and a ratchet mechanism with 42 teeth. This makes it convenient to work even in areas where handle movement is restricted.

The ball-lock release button makes sockets easier to attach and remove.

Bidirectional operation

The ITW 525 allows controlled tightening to a specified torque in both clockwise and counterclockwise directions. This also allows it to be used on left-hand threaded connections, provided the required torque is within the wrench’s operating range.

The ratchet direction switch allows the direction of rotation to be changed quickly without repositioning the tool.

Durable materials

The wrench body is made of 40Cr steel, while the ratchet mechanism components are made of 42CrMo4 steel. The use of appropriately selected steel grades ensures the strength of components subjected to loads during regular use.

With a length of 240 mm, the wrench weighs only 265 g, making it easy to handle during precise service work.

Individual factory calibration certificate

Each wrench has a unique serial number and is supplied with an individual document confirming testing and factory calibration. The document contains the accuracy test results and confirms that the wrench complies with the requirements of DIN EN ISO 6789-1:2017.

Case included

The wrench is supplied in a practical case that makes storage and transport easier and protects the tool against accidental damage and dirt.
