Product Description
This mechanical torque wrench features a preset mechanical design for fastening, assembly, installation, and maintenance work requiring accurate torque control. With clockwise accuracy better than ±3%, it helps users tighten nuts, bolts, and other fasteners according to specified torque requirements, reducing the risk of over-tightening or under-tightening.
The wrench is equipped with a pull-down locking mechanism for convenient torque adjustment and locking. A quick-release button allows fast socket changes, improving efficiency during repair and assembly work. Available in 1/4″, 3/8″, 1/2″, 3/4″, and 1″ drive sizes, with torque ranges from 5–25N·m to 200–1000N·m, it supports applications from precision assembly to heavy-duty industrial maintenance.

FAQ
Q1: How does a mechanical torque wrench work?
A1: Set and lock the desired torque value before use. When the applied torque reaches the preset value, the wrench gives a mechanical click and/or release indication, signaling the user to stop applying force.
Q2: What does “clockwise accuracy better than ±3%” mean?
A2: It means that under normal clockwise operating conditions, the difference between the actual output torque and the set torque is within better than ±3%. Refer to the product manual, test conditions, and calibration results for exact specifications.
Q3: What is the purpose of the pull-down locking mechanism?
A3: The pull-down locking ring locks or unlocks the torque adjustment mechanism. Unlock it to set the torque, then lock it to prevent accidental setting changes during use.
Q4: What does the quick-release button do?
A4: It allows sockets to be attached and removed quickly, improving efficiency when changing socket sizes.
Q5: Can it be used for vehicle wheel lug nuts?
A5: Yes. Select a torque range that covers the vehicle manufacturer’s specified torque value and use a matching socket. A 1/2″ drive torque wrench is commonly used for passenger vehicle lug nuts, but always follow the actual torque requirement.
Q6: Should the wrench be reset after use?
A6: For preset mechanical torque wrenches, it is generally recommended to return the setting to the lowest specified scale value before long-term storage, but not below the minimum setting. Always follow the instructions for the specific model.
Q7: Can it be used to loosen seized bolts?
A7: No. A torque wrench is designed for accurate tightening and should not be used as a breaker bar or for loosening seized or rusted fasteners. Use a breaker bar, socket wrench, or impact tool instead.
Q8: Do you offer calibration and customization?
A8: OEM/ODM options are available. Calibration certificates, scale units, torque ranges, drive sizes, and packaging can be confirmed based on order requirements.
