DETAILED NOTES ON HEAD SCREW TYPES

The helix angle would be the angle concerning the thread’s helical path plus a line perpendicular on the screw's axis of rotation. Usually, a lead screw with a higher helix angle reveals lowered frictional losses and therefore bigger performance.This allows the screwdriver to have superior Make contact with with the screw head. The end result is

The threads-per-inch tells you what number of threads you may have for each inch/centimeter of screw. With an individual thread design (most screws) this can also be the volume of situations the thread wraps across the screw in a single inch/centimeter. The pitch, However, gives you the distance among two adjacent threads. Possibly of those figures
