Seekonk SM-Series Adjustable Click Type Torque Wrenches utilize a micrometer type adjustment mechanism to allow selection of torque value within the capacity of the tool.
Twist locking action prevents accidental changing of torque settings.
When selected torque value is achieved, a distinct click is felt and heard, followed by a sudden release through several degrees of free movement
