Wera Series 7400 VDE Kraftform Adjustable Torque Screwdriver Handle.

This VDE adjustable torque screwdriver handle has been individually tested at 10,000 volts to ensure safe working up to 1,000 volts in accordance with IEC 60900. The adjustable Kraftform handle has been designed to fit perfectly into the hand to allow for a fast, comfortable and ergonomic screwdriving experience. The handles hard zones glide like wheels across the hand for high working speeds, while soft zones provide grip to ensure high torque transfer and comfort during intensive use. A hexagonal anti-roll feature prevents any unwanted rolling off surfaces at the workplace. The handles Torque value can be adjusted from 1.2-3Nm. When the desired pre-set torque value has been reached a distinct audible and perceivable excess load signal triggers. Unlimited torque can be transferred for loosening seized screws. When inserting interchangeable blades a clamping mechanism locks the blade securely, to release the blade simply pull down on the clamping sleeve.
