扭力螺丝刀紧固件的联结质量直接影响到各种仪器仪表、机电设备、家用电器等产品的使用质量至这些产品的可靠程度。所以扭力螺丝刀等扭力工具在工业生产中也逐渐被使用的越来越多了。

扭力螺丝刀用于检测已固定在物体上的螺丝或螺帽的松紧程度，测量螺丝或螺帽旋入或旋出时的扭力。有跟随模式，实时模式和峰值保持模式，测量正反方向扭力。

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 100% 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.
