The “DWA” series of electronic torque and angle wrenches is the best solution for nearly all threaded fastener applications. Even the simple application of nuts and bolts in today’s efficient assembly designs often require a torque pre-load for proper seating and a subsequent angular rotation for proper loading. This wrench employs the recent evolution of precision torque and angular-momentum sensing to control both parameters sequentially in a single continuous motion of the wrench. It locates itself anywhere in space to provide a positional reference for angular rotation of the handle around the integral ratcheting square-drive axis.
An intuitive user interface works with the high-contrast LCD display to show torque and angle preset values, display modes and units selection, “ft-lb,” “in-lb” and “Nm”. Its real-time digital readout (auto track mode) emulates the precision of a dial type torque wrench. Its torque and angle preset function emulates the familiar click-type torque wrench by producing a handle vibration, LED indicators and an audible alert at torque and/or angle preset measurement. Tri-colored LED’s provide real-time early-warning, torque/angle attainment and over-torque alert. The display also captures peak torque readings in tightening or loosening directions, generally CW to identify maximum torque installations and CW or CCW break-away torque for quality audits of preinstalled fasteners.
