Product Overview

Different jobs call for different torque, and a single adjustable driver spanning a wide range often means less precision where you need it most. The Wera 7440/41/42 set solves this with three purpose-built torque screwdrivers instead of one compromise: 0.3–1.2 Nm and 1.2–3.0 Nm for fine, low-torque work, plus a 3.0–6.0 Nm driver with a Kraftform pistol handle for stronger leverage as torque demands increase. Each driver lets you set the required torque by hand, no special tools needed, and reads out on an easy-to-read scale. When you hit your pre-set value, a distinct audible and tactile signal tells you to stop — calibrated to ±6% accuracy per the DIN EN ISO 6789 standard, so the number on the scale is verified, not estimated. The Rapidaptor quick-release chuck on every driver accepts standard 1/4"""" hex bits. Push a bit in and it self-locks the moment it contacts the screw; push the sleeve forward to release it, even the smallest bits, without extra tools or disturbing your torque setting. And because the torque limit only governs driving, you still get unlimited torque to break loose a seized screw. This 27-piece set includes 24 bits — TORX, TORX PLUS, and Hex-Plus profiles — giving you the fastener coverage most electronics and machine assembly work requires. Everything travels in a stable, high-quality case, keeping the full torque range and bit assortment organized and ready.
