_x000D_ About product ESQ preset torque driver is used for torque required thread tightening tightening parts. The product operates clockwise and can preset the fixed torque value. After the set point driver idling, the thread tightening can be controlled first. It is suitable for precision instrument screw locking, circuit board fixing and other high requirements for screw locking and high locking precision requirements. Widely used in a variety of electrical, light industry, machinery manufacturing, scientific research structure and other industries. Feature 1.Can preset torque value, and have audible alarm prompt. When the tightening torque of the fastener reaches the preset torque value, it can automatically send out a signal "click" sound, accompanied by obvious feel vibration, indicating that the work is completed. After the force is removed, each relevant part is automatically reset. 2.Clockwise use, the opposite direction can be disassembled, simple and convenient. 3.Using the straight line scale with the zero point indication, the scale line reading is clear and accurate. 4.The coat is made of nylon material, strong and wear-resistant. 5.The torque driver shall implement the relevant provisions of GB / T 15729-- 2008.
