ST3 is available in SI units in Japan. ST3-G CPT-G series products are manufactured for the global market and offer a selection of SI, metric and American units of measurement.

Spintork® ST15N3-6.35 (L' = 106.5[mm])

Spintork® ST50N3-3/8 (L' = 75[mm])

Spintork® ST1000N3-BT (L' = 135[mm])

Application

  • Checks nutrunner torque and angle on multi-spindle tightening equipment.
  • The ST3-BT and ST3-G-BT series are especially useful for checking torque and angle for rotation angle tightening into the plastic range.
  • Often used to good effect as a measuring device (standard accessory) for multi-spindle equipment nutrunners.
  • Checks the torque and angle of angle power tools and hand nutrunners.
  • The ST1000N3 is ideal for torque checking (routine inspections) of TW2 series torque wrenches used to tighten the wheel nuts of large vehicles, and the DQLE1000N2 torque wrench.

Features

  • Digital torque checkers. The world’s most compact rechargeable rotary torque measuring equipment. (Patented)
  • Nutrunner torque checks (routine inspections) can prevent the production of imperfectly tightened items.
  • Lets operators perform torque checks (routine inspections) of multi-spindle tightening equipment while tightening at the same time. Connecting the optional extension bar, which has the same length as the ST3, to spindles not installed with Spintork® makes it easy to check torque without removing the nutrunner from multi-spindle tightening equipment. This reduces steps in the manufacturing process.
  • Nutrunner inline measurement is possible. If the model is Bluetooth® equipped, torque checking can be cordless, improving workability.
  • ST3 and ST3-G are equipped with an angle sensor. If tightening is done with a handheld nutrunner attached to the ST3 or ST3-G, torque checking and angle checking can be done at the same time as tightening operations. (* Note: Angle measurements are measurements from set snug torque values.)
  • When the supplied USB connecting cable is connected to a PC, tightening torque and angle data determined through measurements using a ST3 or ST3-G SpinTork Rotary Peak Torque Meter can be spread and controlled in Excel format using ExRcv for ST3. (ExRcv for ST3 is available for downloading free of charge.)
  • The ST3-BT and ST3-G-BT can be used to create torque and angle graphs. With a Bluetooth®-equipped ST3-BT, torque and angle can be measured and recorded continuously, and tightened-to-completion data is transmitted wirelessly to a PC. Then after ExRcv for ST3 spreads the data on an Excel file, graphs displaying tightening torque and angle values can be created. (* Note: You need to have your own software for Bluetooth® signal reception.) (* Note: When the ST3 is not the -BT version, memory stores only angle data at time of recording and maximum torque, and graphs cannot be created.)
  • Bit types and small square drive models have been added to the lineup. Newly added: ST15N3-6.35, which can be attached to Hex 6.35 bit tools (not available on older ST2 series), and ST50N3-3/8 9.53 square drive (smaller than previous version).
  • Excel Receiver software is a data input tool for Excel® data management. It can be downloaded for free. * Note: Excel® is a registered trademark of the Microsoft Corporation.
  • A Tightening Data Management System can be created for Bluetooth-equipped ST3-BT / ST3-G-BT series devices, through use of the special custom-modified TDMS / TDMSHT.
