The phrase socket head capscrew generally refers into a type of threaded fastener whose head diameter is nominally 1.5 instances that with the screw shank (important) diameter, using a

The helix angle may be the angle concerning the thread’s helical route along with a line perpendicular to your screw's axis of rotation. Normally, a lead screw with a bigger helix angle displays decreased frictional losses and thus larger effectiveness.Despite getting a small point in elaborate assemblies, a lead screw may be damaged down into 3
