The smallest and lightest battery torque wrench on the market with torque capabilities up to 4,000 Nm (2,950 ft*lbs), developed by ITH Bolting Technology, has the best power-to-weight ratio (Nm/kg) of its class coupled with an industry-leading battery capacity of 5.2 Ah.
The ITH type ADS also features a brushless – and thereby wear-free – motor with automatic shut-off when the target torque value is reached.
