扭力螺絲刀緊固件的聯結質量直接影響到各種儀器儀表、機電設備、家用電器等產品的使用質量至這些產品的可靠程度。所以津源扭力螺絲刀等扭力工具在工業生產中也逐漸被使用的越來越多了。

扭力螺絲刀用于檢測已固定在物體上的螺絲或螺帽的松緊程度，測量螺絲或螺帽旋入或旋出時的扭力。有跟隨模式，實時模式和峰值保持模式，測量正反方向扭力。

TSD-50: Measuring Range: 0.45 - 4.50 lb-in / 5.0 - 50.0 cN-M (0.05 - 0.5 Nm)
TSD-400: Measuring Range: 3.50 - 35.00 lb-in / 40.0 - 400.0 cN-M (0.4 - 4 Nm)

TSD digital torque screwdrivers are designed for accurate measurement of application and removal torque of screws and fasteners. The TSD measures bi-directional torque in real-time or peak modes. 9 programmable target values can be preset to allow the operator to quickly fasten screws using audible and visual indicators to alert when the target value is reached or passed.

The TSD uses standard 1/4" hex bits allowing it to be used on a wide range of applications. An auto-locking bit holder allows for quick changing between sizes.
