1. Core role

Tighten the bolt/nut: Clamp the head of the bolt/nut through the wrench jaws, apply torque using the lever principle, and tighten it to a tightened state (such as equipment assembly, parts fixing).

Remove bolts/nuts: Apply reverse torque to loosen or remove loose, rusty (with penetrant) or bolts/nuts to be replaced (such as repair and replacement of parts, equipment disassembly).

Auxiliary clamping: Temporarily clamp small workpieces (such as pipes and rods) to prevent slipping during operation (care should be taken to avoid scratching the surface of the workpiece).

 

 

2. Main uses (classified by scenario)

1. Home/Daily Scenes

Furniture installation/maintenance: Tighten screws when assembling tables, chairs and wardrobes, and repair fixing nuts for door and window hinges and handles.

Home appliance repair: Remove the housing fixing bolts of washing machines, air conditioners, water heaters and other home appliances, and replace accessories (such as air conditioner filter fixing screws).

Pipe maintenance: Tighten or remove nuts from faucets and water pipe joints (it is recommended to use anti-slip pads to avoid scratching metal surfaces).

Daily emergency: Loosen rusty bicycle screws, door and window lock fixtures, etc.

 

2. Industrial/engineering scenarios

Mechanical maintenance: maintenance of machine tools, motors, water pumps and other equipment, removal of equipment casings, bearing end caps, and connecting bolts.

Construction: Tighten temporary fixing bolts during steel structure installation, nuts connecting pipes and valves during water and electricity installation.

Automobile maintenance: Remove automobile tire nuts (small adjustable wrenches are suitable for light vehicles) and engine peripheral accessory bolts (such as generator, air conditioning compressor fixing screws).

Water, electricity/HVAC: Install or repair flanges and joint nuts for water pipes, heating pipes, and gas pipes.

 

3. Outdoor/Emergency Scenes

Field work: Build tents, fix equipment brackets, and repair outdoor tools (such as generators, water pumps) during camping.

Emergency rescue: Temporarily tighten or remove connecting parts of damaged equipment and pipelines to quickly handle faults.

 

4. Other professional scenarios

Electrical work: Tighten the fixing bolts of the distribution box and junction box (insulating gloves need to be used to ensure safety).

Agricultural machinery maintenance: Remove the fixing bolts of agricultural machinery parts such as tractors and harvesters, and adapt them to different specifications of agricultural machinery accessories.

 

3. Key usage points (improving efficiency + protecting tools/workpieces)

1.When adjusting the opening, ensure that the jaws fit tightly against the head of the bolt/nut to avoid slipping and scratching corners (give priority to allowing the fixed jaws to withstand the main force).

 

2.When applying torque, the wrench should be perpendicular to the axis of the bolt/nut to avoid slipping and injuring people or damaging tools due to oblique pulling.

 

3.Select an adjustable wrench of appropriate specification according to the size of the workpiece (common specifications: 6 inches, 8 inches, 10 inches, and 12 inches) to avoid deformation of the tool due to tightening large bolts with small wrenches.

Rusty or overtight bolts/nuts, spray penetrating agent (such as WD-40) to infiltrate them first. Do not twist them violently to prevent bolt breakage or wrench damage.

 

4.It is forbidden to put a sleeve on the handle of the wrench to extend the arm (which may cause the wrench to break), and do not hit the wrench with a hammer (which may damage the adjusting screw and jaws).
