Smart Torque Wrench

Item No：M18316--M18319

 

Product advantages and characteristics：

Bidirectional ratchet head for easy forward and reverse switching.

Data can be transmitted to a PC via WiFi (Note: WiFi is an optional feature).

Capable of storing 999 sets of torque values. Accuracy level: CW ±2%, CCW ±2%.

Equipped with an LED display, RGB tri-color indicator lights, and a buzzer to prevent torque overload.

ABS handle designed according to ergonomic principles.

The handle is made of alloy tubing with overall heat treatment, making it resistant to deformation.

 

 

1. Core role (three core functions)

1.Precise torque control

Built-in high-precision torque sensor (accuracy usually reaches ±1%~±2%) converts the torque value into a digital signal in real time, and displays it intuitively through the LCD/LED screen (units can be switched N·m, kgf·cm, lbf·in, etc.) to avoid the errors of "estimating readings" in traditional mechanical wrenches.

Support preset torque values, and use sound and light alarms (beep + flashing indicator light) or vibration reminders when the set torque is reached to prevent over-tightening (causing bolt fracture and thread damage) or under-tightening (causing loose connection and equipment failure).

 

2.Data recording and traceability

Some high-end models support storing torque data (hundreds to thousands of pieces can be stored), recording tightening time, torque value, operator and other information, exporting it to a computer via USB /Bluetooth, and generating reports (suitable for quality control and compliance audits).

Some support networking functions, upload data to the cloud in real time, and realize collaborative management and remote monitoring of multiple devices (Industry 4.0 scenario adaptation).

 

3.Convenient operation and multifunctional expansion

It has basic functions such as torque unit switching, clearing, peak holding (locking the maximum torque value), and continuous measurement. Some models support torque calibration (self-calibration or external calibration) to ensure long-term accuracy.

Adapt to different scenarios: It can be used with sleeve, quincx head, and open head. It supports positive and negative bidirectional torque measurement (both tightening/loosening are available), and some have angle measurement functions (torque + angle dual parameter control, suitable for fastening scenarios that require precise corners).

 

2. Subdividing purposes (classified by industry/scenario)

1. Automobile manufacturing and maintenance (core application scenarios)

Assembly: Key components such as engine cylinder head bolts, crankshaft bolts, hub nuts, and gearbox screws must strictly follow the torque specified by the manufacturer (for example, insufficient torque of cylinder head bolts will cause air leakage, and over-tightening will damage the cylinder block), intelligent Digital wrench ensures consistency.

Maintenance: Tighten hub nuts when replacing tires (to avoid loosening during driving), assemble brake systems, repair suspension parts, etc., especially battery pack bolts and motor fixing bolts for new energy vehicles, which require extremely high torque accuracy (affecting safety and battery life).

After-sales quality inspection: Record the torque data during the maintenance process to facilitate fault tracing (if the component becomes loose after maintenance, check whether the tightening torque is up to standard at that time).

 

2. Industrial production and manufacturing

Mechanical processing: Assembly of machine tools, robots, and automated equipment, such as bearing fixing, gearbox connection, and guide screw tightening, torque accuracy directly affects the operating stability and service life of the equipment.

Electronic and electrical appliances: Fixed new energy battery (power battery, energy storage battery) modules, and assembled core components of home appliances (air conditioning compressor, washing machine motor) to avoid excessive torque damaging electronic components or plastic structures.

Aerospace/rail transit: High-end equipment manufacturing (such as aircraft parts, high-speed rail carriage connections) has strict requirements for torque consistency and data traceability. Intelligent digital wrench is an essential tool for compliance production (some scenarios must comply with ISO 9001, AS9100 and other standards).

Hardware and building materials: door and window hardware, furniture assembly (such as fastening of customized furniture screws to avoid over-tightening and causing cracking of wooden boards), can improve efficiency and ensure product quality during mass production.

 

3. Construction and infrastructure projects

Steel structure installation: Bolts for factories, bridges, and high-rise steel structures (such as high-strength bolts) need to be constructed according to the design torque value to avoid structural loosening or uneven stress. Intelligent digital wrench can ensure that construction complies with specifications.

HVAC/pipe installation: Pipe flange connection and valve fixing, insufficient torque will cause water/air leakage, excessive tightening will damage the seals, and the digital display function can accurately control the tightening force.

 

4. Scientific Research and Laboratory

Material mechanics testing: Conduct a torque loading test on the test piece, record the torque-deformation curve, and use it for material strength research (such as fatigue resistance test of bolt material).

Product development: When assembling a new product prototype, test the impact of different torques on product performance and optimize design parameters (such as the relationship between screw torque and vibration noise of home appliances).

 

5. other scenarios

Agricultural machinery maintenance: For the maintenance of engines and chassis components of agricultural machinery such as tractors and harvesters, the digital display is clear and readable during outdoor operation, and the alarm function can avoid errors in empirical operation.

Fire-fighting equipment: Fixing bolts for fire extinguishers, fire hydrants, and fire pipes must be tightened according to fire regulations to ensure normal use in emergencies.

 

3. Key to selection (core parameters for matching purposes)

Torque range: Select according to the scenario (such as 5~300N·m for automobile maintenance, 0.5~50N·m for electronic equipment, and 100~1000N·m for industrial heavy equipment).

Accuracy level: ±1% FS (full-scale accuracy) is preferred, and higher accuracy is required for key scenarios (such as ±0.5% FS for aerospace).
