Bolt tension monitors are highly sensitive Ultrasonic meters used by industries to measure bolt load, elongation, stress, and percentage of strain on threaded fasteners. Bolt Tension Monitors are instruments designed to monitor stresses on threaded fasteners for delivering precise bolt loads to the joint.
