Part# 12-03403
MFR Model# 869761


Micrometer Adjustable Ratcheting Square Drive torque wrenches are ideal for any application where:
  • The fastener or fitting to be tightened can be engaged with a socket.
  • The user changes from one torque to another often.
  • A high amount of rotation or limited access requires ratcheting to achieve the desired torque.
  • The ability to select the torque and lock it in rapidly is needed.
  • Simplicity of operation is needed.
  • Very high durability is needed.
These needs are common in small quantity assembly operations and many maintenance functions; the SDR-Series tools are superb for these types of applications.
