Chiave dinamometrica regolabile, chiave dinamometrica preimpostata, chiave a cricchetto da 1/4 pollici (5-25 Nm)

Drive head size: 1/4 inch Torque range: 5-25 Nm High precision: This range indicates that it is a preset torque wrench. You first set the required torque value (e.g. 10Nm) using the scale or knob on the wrench. Working method: As you tighten the screws, the applied torque gradually increases. When the actual torque reaches your preset value (10Nm), the wrench will make a clear "click" sound accompanied by a tactile "release" sensation, prompting you to immediately stop applying force. This ensures that the torque is precisely controlled, neither too tight (causing slippage or breakage) nor too loose (causing looseness). Protective: It is a key tool for protecting precision parts and screws. This is a torque wrench suitable for precision and small mechanical maintenance. It uses a 1/4 inch socket attachment and can accurately set and output torque within the range of 5 to 25 N · m.
