RECOMMENDATIONS FOR USING PRESS AL SCREWSLEN
-
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 key;
-
Be careful with the measurements as we have screws in millimeters and inches;
-
Check the hardness of the screws: 8.8, 10.9 or 12.9 (maximum resistance);
-
Check if the taps used are compatible with the hardness step of the screws to be used;
-
See if the screw support faces 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 beating the threads;
-
Always have spare screws in case of replacement;
-
Use correct Allen wrenches to avoid "popping" the hex;
-
Change the screws regularly as they also sufferm mechanical fatigue over time;
-
Avoid oxidation of them.
