Features
- Made of carbon steel material for wear resistance and durability.
- Rubber handles for anti-slip and comfort grip.
- Used to fasten or remove round nuts and water meter covers on machine tools and machinery.
- If the nut diameter is within the limits of the wrench specification range, it is suitable for a wrench of that size.
- Easy to use, practical and convenient.
How to choose a wrench size
When choosing the size of the wrench, measure the round nut/product outer diameter. For example, the diameter of 42mm can choose a slightly larger wrench, that is, 45-52mm, so the circled arc is greater, the torque is greater, and it is convenient to unscrew/tighten the nut.
