Hand tools meet semiconductors
Stand Tools did what few tool makers dared: develop hand tools that integrate nanotechnology, electronic engineering, semiconductors, mechanics and IC design. The result was the first universal digital torque wrench made in Taiwan.
Three disciplines, one tool
Semiconductor technology
Taiwan has some of the world's best semiconductor manufacturing. We apply it to make all electronic parts, including the sensor, for greater accuracy, lower cost and shorter lead times.
Dedicated IC design
A special IC processes the sensor data with complex formulae to calculate the torque value and show it on the display — so anyone can read the exact torque.
Mechanical engineering
We analyse torque, shear-stress and pressure diagrams to design the best mechanical structure, making every wrench more comfortable and efficient to use.
Every DG®-II is calibrated in-house
We started building our calibration laboratory in 2008. Our laboratory procedures follow ISO/IEC 17025, and our hand torque tools are calibrated in accordance with ISO 6789.
Every DG®-II is inspected and supplied with its own calibration report.

Physics first, electronics second
Torque is generated from a known force applied over a defined lever arm.
g — local gravity
Gravity is a critical parameter in calibrating torque tools. The gravity in our laboratory was measured at 978,821.964 mGal by Taiwan's National Science Council.
Gravity weights
From Newton's second law, F = m·g. To create a correct torque over a fixed length, we hang gravity weights (force) on the beam — not mass weights.
The beam
A beam loaded with gravity weights produces a stable, reliable torque that staff can see physically, without relying on an electronic display. We were the first in the industry to calibrate DG®-II this way.
Calibration machines
Our calibration machines are designed in-house from the basic principles of physics. Results are recorded by computer for quality control of every wrench.
When an extension changes the effective lever arm, calculate the corrected wrench setting with the Torque Wrench Extension Calculator.
