100 cN·m = 1 N·m. Slip type: the driver slips once the set torque is reached.

Interchangeable ratchet heads

Model Drive Fits wrenches with Weight (kg)
QH12D 3/8" "X12D" 0.19
QH15D 1/2" "X15D" 0.3

How to choose

  1. Check the unit. Screw specs are often in cN·m (drivers); bolt specs in N·m (wrenches).
  2. Pick a range that puts your target torque in the middle, not at the very bottom or top.
  3. Set-and-click vs. read-the-value. Preset (QL, CL, MTQL, RTD) is for repeat tightening; dial (DB) and plate (F) types show the value, useful for checking.
  4. Match the drive to your sockets: 1/4", 3/8" or 1/2".
