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。

GLK Digital Torque Screwdrivers are compact, lightweight, and feature, LED?ａnd audible alarms, ergonomic handle, push button controls, and are battery powered. 

Measure torque in peak or real time modes. Auto zero mode resets peak measurements automatically (1-10 seconds). Selectable units of ozf-in, lbf-in, and N-cm. 

Five programmable torque presets stored in memory enable the user to check frequently used values. The presets alert the user with an intermittent signal at 90% and a continuous signal at 99% of the preset torque value using LED?ａnd audible indicators which enable users to tighten to within 10% of a preset torque value. 

Pass/Fail mode counts the number of fasteners tightened within programmed high and low torque limits.
