MMTB Miniature Break-Over Wrench


+ Enlarge Picture

  

The MMTB is miniature preset production torque wrench with a fixed head. The versatile wrench is available with different head configuration options, like open, box, flare, hex key and ratchet head. MMTB models are design to have one permanent head style attached to it. When the TB torque wrench achieves torque, the head breaks-over preventing the operator from overtorquing the fastener.

Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789:2003 (+/- 6% of setting).

 
  • "Breaks-over" when preset torque is reached eliminating overtorquing.
  • The break-over mechanism minimizes shock to assemblies.
  • Tamper-proof internal adjustment. No external adjustment scale - must be preset using a torque analyzer.
  • Torque Ranges from 1 ozf.in to 80 ozf.in.
  • One-way operation standard.
  • Bi-directional break and calibration available.
  • Small with lightweight aluminum handle
    (3/8" dia. x approx.- 3 1/2" overall length).
  • To configure the TB fixed head wrench, select Handle part number below and select interchangeable head part number. Example: 06004C-156.

Roller Grip Head
The Roller Grip Heads are custom made; provide size information (sample preferred) and any clearance issues. Head can be used for round knurled or nonknurled nut(s) where gripping to tighten might damage the surface. Typically, for odd sizes and with no flats for a wrench head to grip. Also, can be used to tighten certain tube shapes that wouldn’t collapse under torque pressure. Maximum torque capacity for the head is 2 lbf.in
