- Always use cold forged and standardized Allen screws (SAE - 1429, ISO-898, IFI-104 AND UNI) as they facilitate their application and replacement;

- Check the series being used - 1936 or 1960, as there is a difference in the height of the head and the key;

- Take care with the measurements because we have screws in millimeters and inches;

- Check the hardness of the screws: 8.8, 10.9 or 12.9 (maximum strength);

- Check if the taps used are compatible with the step of hardness of the screws to be used;

- See if the support faces of the screw are parallel with those of the parts;

- Check that the holes are perpendicular to the face of the part;

- Do not use pipes or extensions for tightening;

- Always use a torque wrench;

- Avoid hitting the threads;

- Always have spare screws, in case of replacement;

- Use correct Allen keys to avoid hexagonal "flow";

- Change the screws regularly as they also suffer mechanical fatigue over time;

- Avoid oxidation.
