Wera Kraftform Micro Electronic Screwdrivers are designed to reduce the fastening time and cost per screw connexion. The electronic TORX HF screwdriver with holding function literally presses the screw onto the screwdriver. The conical driving flanks that taper twords the tip of the tool, the optimised flank base and the ideal engage depth hold the screw securely on the blade. Kraftform Micro handle features the shape that facilitates high torque transfer and precision feel for fine adjustment work. Hand support on convex/concave cap offers both an easy turning action and comfortable hand rest. The slim fast-turning zone, beneath the cap, accelerates the screwdriving process and reduces time-consuming grip adjustments. Integrated soft zones in handle bulge, transfer high tightening/loosening forces without losing contact with screws. Precision zone at blade provides better feel for rotational angle during fine adjustment work. Wera black point Tip and hardening process guarantee long service life and increased corrosion protection. Anti-roll protection stops screwdrivers from rolling away at the workplace.
