5- Minor Diameter: The slight diameter is the smallest diameter in the thread, calculated among the two Opposite roots for your screw shaft and amid contrary crests for that nut.
This metric is usually A part of the producer's technical specs. A lead screw with a scaled-down lead precision benefit implies larger precision and precision.
Countersink Also refers to the identify in the drill little bit which is utilized to Slice such a gap. A conventional hole punched into your leading of the screw gap that permits the screw to lie flush with or beneath the area of the material staying pushed into.
