DPSK torque screwdriver

The DPSK Torque Screwdriver

Its measuring principle is based on the deformation of a spring blade: the blade’s torsion is directly visible on the circular scale, without any complex mechanisms or electronics. This simple, robust design ensures a long service life and virtually no maintenance.

A preload mechanism eliminates backlash between 0 and the preload torque, making repetitive operations on the production line easier.
The DPSK is available in two versions: the standard model with a classic dial, and the DPSK II with a transparent dial that allows you to see the tip directly through the scale, making it easier to position the tool on screws in tight spaces.

The series covers a range from 2 to 500 cN·m (6 models), with an accuracy of ±3% across the entire measurement range.

Applications of the DPSK torque screwdriver

The DPSK torque screwdriver is used in all industries where torque-controlled tightening of small fasteners is required:

Inspection and Quality Control

Verification of screw tightening torque on finished assemblies; monitoring of removal torque to detect under-tightening or over-tightening during manufacturing.

Tensile tests

The DPSK is particularly well-suited for unscrewing strength tests, enabling the measurement of the breaking torque of screws, inserts, or threaded connections up to their strength limit.

Electronics and Precision Mechanics

Tightening and inspecting small precision screws on circuit boards, measuring instruments, medical equipment, and optical devices.

Luxury cosmetics and packaging

Monitoring the tightening torque of small caps, lids, and mechanisms on bottles of high-end perfumes and cosmetics.

Maintenance and Adjustment

Checking the torque of assembly screws during maintenance operations on industrial equipment or in repair shops.

Why choose a torque screwdriver with a dial instead of a trigger?

Trigger-type screwdrivers (such as the LTDK or STDK) are designed to apply a preset torque repeatedly. They are ideal for assembly line screwdriving.

The DPSK addresses a different need: measuring the actual torque applied in real time, without any prior calibration.
That is the fundamental difference between a clamping tool and a measuring tool.

The DPSK is essential in situations where you need to know the exact torque value to validate a process, diagnose a tightening issue, establish specifications for a new part, or perform a documented breakaway test.

Its direct dial reading, with no digital display or battery, also makes it a particularly reliable tool in production environments where simplicity and immediate availability take precedence over connectivity.
