What’s new?

For more than 25 years, the HYTORC MXT has been the world's best-selling, most used and probably the most copied torque wrench. Also known as the mother of all hydraulic torque wrenches, MXT has finally been updated after HYTORC has released a new product from its legendary wrench model.
HYTORC MXT on maailman suosituin hydraulinen momenttiväänninmalli
Haitor’s calibration laboratory has been granted the only accreditation for torque in Finland which meets the SFS-EN ISO / IEC 17025: 2017 requirement. In the future, the scope of our accredited torque calibration service will be even wider, with the measuring range of hydraulic torque wrenches reaching up to 100,000 Nm.
