Kraftform 7431 ESD adjustable torque screwdriver 0.30-1.00 Nm, 1/4" Rapidaptor - Wera 05074782001

When screws on electrostatically sensitive assemblies have to be tightened to a defined torque, the Kraftform 7431 ESD can be set by hand to any value between 0.30 and 1.00 Nm, without any special tools. A distinctly audible and noticeable signal indicates when the pre-set torque is reached.
