Torque wrench

The dynamometric key is a precise measuring instrument of the moment of strength. It is used to twist threaded fasteners so that the moment of connection is known and suitable for the type of material and the strength of the screw and nuts. The key consists of a head with a square mandrel and arm transferring strength. The head is used to attach hexagonal caps. Comparative statement of moments in various units of length and force: 1 kg*cm = 13.887 OZ*in (ounce X inch) 1 kg*cm = 0.867 LB*in (Punish X inch) 1 kg*m = 9,80665 n*m ( Niuton x meter) 1 kg*m = 7,233 lb*ft (pound x foot) 1 ft*lb = 12 lb*in (pound x inch) 1 dm*n = 14.16 oz*in (ounce x inch) is used Mainly in automotive technique for precise fastening and wherever the manufacturer determined the required time of tightening the connector.
- Choose the appropriate NM or In-LBS scale. Unscrew the blocking screw at the end of the micrometer knob.
- Place the micrometer knob so that "0" on the scale of the knob covers with a vertical line on the key's shoulder. - rotate the micrometer knob according to the direction of the clockwise movement until the requested torque is set. The desired torque is set when the scale on the micrometer knob will cover with the vertical line on the key's shoulder.
- Then turn the lock screw to the resistance and set the appropriate direction of rotation of the rattles, after which the key is ready for use.
- Apply the appropriate attachment to the key load. When tightening, reaching the set moment is signaled by clicking the key. If you hear or feel the click, stop tightening. - dynamometric key - user manual - warranty card - suitcase
