The Birzman Torque Wrench 10-60Nm (Bi-Directional) is a precision-engineered workshop tool designed for controlled fastening and loosening operations on compatible bicycle components. Featuring an adjustable torque range of 10–60 Nm, a 1/2-inch square drive, and a 72-tooth ratchet mechanism, this torque wrench is suitable for professional bicycle mechanics, workshop technicians, and experienced home mechanics who require controlled torque application during bicycle assembly and maintenance.
The wrench allows torque adjustment in 0.5 Nm increments, providing flexibility when setting the required value within its specified range. Its clear measurement scale helps users identify the desired torque setting, while the adjustable collar on the handle allows the setting to be changed. To adjust the torque, pull down the collar and rotate it until the indicator aligns with the required value, following the manufacturer's operating instructions.
Designed for both left-hand and right-hand threaded applications, the Birzman Bi-Directional Torque Wrench incorporates a 72-tooth ratchet mechanism in either direction. This supports controlled operation when working with compatible fasteners. Its 1/2-inch square drive accepts suitable compatible accessories, while the non-slip handle is designed to provide a secure and comfortable grip during workshop tasks.
