7400 ESD series Kraftform Torque screwdrivers, with factory pre-set value (0.1-1.5 Nm) and Rapidaptor quick-release chuck, handle size 89 mm

Single-hand function

Every function of the Rapidator quick-release chuck, such as inserting or releasing bits, can be carried out with one hand. This is faster, more economical and more ergonomic. There are no unnecessary manoeuvres.

Kraftform

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.

Factory pre-set, adjustable Kraftform ESD torque screwdriver
ESD-safe tool thanks to surface resistance of ≤ 10⁹ Ohm
Kraftform handle for fast and ergonomic screwdriving
Suitable for bits with 1/4" hex head drive
Rapidaptor quick-release chuck for bits with 1/4" hex head drive

Pre-set, adjustable torque screwdrivers

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). Afterwards you can check the set value using an off-the-shelf torque tester.

Wera ESD Tools

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.

High protection

The electric surface resistance of the Wera ESD material is ≤ 10⁹ ohm. This securely protects components against electrostatic energy and associated damage.

Chuck-all

The Rapidaptor quick-release chucks hold ¼" DIN ISO 1173-C 6,3 and E 6,3 as well as Wera series 1 and 4 bits.

Rapid-in and self-lock

The bit can be pushed into the adaptor without moving the sleeve. The lock is activated automatically as soon as the bit is applied to the screw. Bits are held securely and wobble-free.

Rapid-out

Simply push the sleeve forward to change the bit. The spring mechanism lifts the bit off the magnet and unlocks the tool. The bit can be easily removed. The rapid-out function makes it easy to remove even the smallest bits without extra tools.

Article 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. Rapidaptor quick-release technology for rapid bit changes. 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 1/4" hexagon drive as per DIN ISO 1173-C 6.3 and E 6.3 (ISO 1173).
Please note: 1 Ncm = 0.01 Nm.
