The Facom E.506-340S Torque & Angle Adaptor for use in confined spaces to provide torque or angle increments. The electronic display prevents reading errors and tightening is indicated via LEDs and a buzzer. It has 9 torque and/or angle values that can be preset, a 50 result memory, a locking keypad and a magnetised tool (ratchet) fastening. Angle tightening eliminates friction issues related with torque tightening. The movement, and hence faster tension, is defined by the screw pitch and tightening angle. Torque/angle tightening is performed in 2 steps. By pre-torquing to approach the parts and eliminate interface faults. Then tightening at a specific angle. Proper assembly tension prevents the fastener from loosening or breaking. Supplied in a plastic case with a calibration certificate and 2 x AAA-LR03 1.5V Batteries. Specification Torque Accuracy: ± 3°.Angle Accuracy: ± 2°.Capacity: 17-340Nm. Measuring Units: Nm, lbf.ft, lbf.in, kg.cm and deg. Measuring Mode: Peak or Follower.
