Kraftform 7455 ESD torque screwdriver factory pre-set 0.1 Nm (0.1-0.34 Nm), 4 mm Halfmoon/HIOS - Wera 05074826001

Precision screwdriving on electronics requires small and always identical torques. The Kraftform 7455 ESD is factory pre-set to the smallest scale value of 0.1 Nm and gives a distinctly audible and noticeable signal when it is reached, while the surface resistance of ≤ 10⁹ Ohm protects the components.

Benefits

• ESD-safe tool thanks to surface resistance of ≤ 10⁹ Ohm
• Fixed pre-set value for constant torque and high repeat accuracy
• Only adjustable with an extra tool (re-calibration kit 05137003001), then check with an off-the-shelf torque tester
• Quick-release chuck for bits with 4 mm Halfmoon drive (Wera series 9) and 4 mm HIOS drive (Wera series 21)
• Unlimited loosening torque and multi-component Kraftform handle with hard and soft zones

Applications

Series assembly of small screws in electronics production, on smartphones, cameras and circuit boards in ESD protected areas. Please note: 1 Ncm = 0.01 Nm.

Standards and safety

The resistance requirements for ESD screwdriving tools are specified in DIN EN 61340-5-1. Changing the pre-set torque requires a special tool and torque test equipment, please contact the Wera Torque Service.
