Screw is the name given to the grooves opened with helix angle on a smooth cylindrical or conical surface. It is formed by winding it as a helix curve on a cylindrical shaft.
Helix curves are curves with constant curvature and constant torsion functions. Curves that wrap around a cylindrical shaft are called helix. When these angles are small, the holding force of the screw increases. This type of screws are triangular screws. Since these are small in terms of the number of screw pitches, they are more resistant to possible impacts. In motion screws, the number of steps is large.
