In industries, operators will always find themselves daily with the need to perform tightening tasks, either because they must carry out maintenance, or assembly.
Either because they work in the construction of a wind turbine, or in the repair of a vehicle, there will be a need to tighten nuts, joints, etc.
In some of these operations, socket wrenches are used, and the situation may occur in which:
- There is not enough space to perform the tightening task
- The square of the wrench that we are going to use to perform said tightening, is not the size of the square of the socket wrench
It turns out we have a problem. That is where the adapters come in, which allow us to solve the two problems that we have mentioned above.
When using an adapter, we must always ensure that it fulfills its function properly, that it resists a minimum of force applied when performing the tightening.
Put another way: A minimum torque momentum
What is a twisting momentum?
Without going into detail, it is the ability of a force (applied force) to exert a spin, which is a force exerted. This force exerted will depend on:
- The force applied
- The distance between the point where the force is applied, and the point where the rotation is made
- The angle between the point where force is applied, with respect to where the rotation is exerted.
The greater the force applied, the greater the force exerted. And the greater the distance between the point of the applied force and where you want to make the turn, the greater the force exerted.
And the unit of measurement used is the Newton-meter (Nm)
Now that we have a notion of what torsion time is, let's see what we've explained it for.
As we have said, when it comes to acquiring adapters for our tightening tasks, we must make sure of their quality.
And a variable to consider is the minimum torque momentum
It turns out that the key to knowing what momentum, of minimum torque an adapter should hold is in the dimension of its conductive square.
And that is why today we want to leave you this table, which we recommend always having at hand, when evaluating the quality of the adapters that have been acquired:
Square (inch) | Minimum torque test momentum (Nm) |
1/4 | 68.6 |
3/8 | 225 |
1/2 | 569 |
3/4 | 1569 |
1 | 2795 |
So, before you put your adapters to work, make sure they meet the minimum torque momentum.
