What Does types of screw heads Mean?

Buckling load, often known as column power, is the most compressive pressure a lead screw can endure in advance of it begins to bend or buckle.

It is achievable to alter the lead screw efficiency whilst trying to keep a similar diameter and lead by altering the coefficient of friction within the assembly. This is often accomplished by switching the nut material or including a coating on the screw.
