The HDP-50 is for testing the torque of installed screws. ASG or other drivers can be checked and adjusted by comparative tests on a given fastener.

Torque Range - 1.5-100 kgf·cm, 1.5-90.0 lbf·in, .15-.10.0 N·m

These instruments are very sensitive (torque measured to a minimum of .01 kgf·cm), and are particularly useful for checking screws on precision products.

Testers come complete with carrying case, probe, battery charger, three assorted screwdriver bits and a certificate of calibration showing traceability to the National Institute of Standards and Technology. Method of calibration complies with MIL-STD-45662. A detachable cord, designed for easy storage and replacement is included.
