Scope of delivery
- 7400 ESD series Kraftform Torque screwdrivers, with factory pre-set value (0.1-1.0 Nm) and quick-release chuck, 7455 ESD x 0.1 Nm x 0.1-0.34 Nm
Product description
Wera torque screwdriver. Safe protection against electrostatic charge and associated damage. With a factory pre-set torque value set to the smallest scale value. For all applications, where the same constant torque and repeat accuracy are required. The torque can be changed with an extra tool within the measuring range (re-calibration kit can be ordered with the code number 05137003001). Afterwards you can check the set value using an off-the-shelf torque tester. With quick-release chuck for rapid bit change. Unlimited loosening torque for slackening stuck screws. Multi-component Kraftform handle with hard and soft zones for high working speeds, whilst being easy on the hand. Suitable for bits with a 4 mm Halfmoon drive (Wera series 9) and a 4 mm HIOS drive (Wera series 21).
Please note: 1 Ncm = 0.01 Nm.

Features and benefits
- Wera torque screwdrivers. With a factory pre-set torque value set to the smallest scale value. For all applications, where the same constant torque and repeat accuracy are required. The torque can be changed with an extra tool within the measuring range (re-calibration kit can be ordered with the code number 05137003001).

- The requirements for ESD-safe screwdrivers are specified in the European standard DIN EN 61340-5-1. This standard also includes a handle that has to be out of a defined conductive material. The Wera products in the ESD series satisfy these standards and the even more stringent requirements demanded by some technology companies.
- The electric surface resistance of the Wera ESD material is<= 109 ohm. This securely protects components against electrostatic energy and associated damage.
- Features a combination bit holder for both bits with Halfmoon and bits with HIOS drive.
- The basic idea for the prototype of the Kraftform handle - that the hand should dictate the design - has, right through to today, proved to be correct. In cooperation with the internationally recognised Fraunhofer IAO Institute, Wera developed a screwdriver handle designed to match the shape of the human hand as long ago as the 1960s. After a long development phase, the Wera Kraftform handle was launched to the market in 1968. It has been optimised through the years with new technologies, but has kept its proven shape. After all, the human hand has not changed either.
