Torque Wrench Square Drive (TWSD)
Description: The TWSD torque wrench is a ratchet-type torque tool used in conjunction with
standard impact sockets to hydraulically tighten nuts and bolts. It is powered using a 690 bar
(10,000 psi) hydraulic pump unit. The torque output from the TWSD torque wrench is proportional
to the pump-pressure applied.
