A small torque applied to a screw can exert a large axial force on a mass. Therefore, a threaded component is said to produce a Mechanical Advantage.
(a) Helical threading increases the mechanical advantage.
(b) Also provide less inclination whenever heavy load act on it.
(c) Helical threading means increasing pitch so it holds wood more firmly than a screw.
