Torque drivers (cN·m)

Model Type Range (cN·m) Graduation (cN·m) Length (mm) Weight (g, approx.)
RTD15CN slip preset 2–15 0.1 101 50
RTD30CN slip preset 4–30 0.2 101 50
RTD120CN slip preset 20–120 1 132 160
RTD260CN slip preset 60–260 2 149 270
RTD500CN slip preset 100–500 5 155 320
LTD500CN non-slip preset 100–500 Not confirmed 155 330

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
QH15D-3/8 3/8" "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".
