1、Rotation Setting Torque: Adjusting the torque requires loosening the locking device. Increase the torque value clockwise and reduce the torque value counterclockwise. 2、High Strength: 1/4 in preset torque wrench is made of chrome vanadium steel structure, which provides extremely strong durability and impact resistance for various applications. 3、Laser Precision Value: The wrench scale adopts laser technology, and its range scale is clear and precise, easy to read and wear resistant. More convenient to use. 4、Easy To Use: When the adjustable torque wrench set reaches the preset torque value, the torque wrench will make a "click" sound, reminding you to stop applying force to prevent excessive torque from damaging your items. When not in use, please adjust the wrench to the minimum torque value to extend the service life of the torque wrench. 5、Wide Compatibility: Widely used in car spark plug replacement, bicycle and motorcycle maintenance, equipment installation, electrical engineering, product assembly, etc.
