Thread turns per length

Calculates engagement turns from engagement length and pitch.

Calculates helix angle from lead and pitch diameter.

Calculates thread lead from pitch and user-supplied number of starts.

Calculates approximate thread depth from a pitch multiplier; it is not a standards-based inspection dimension.

Calculates simplified thread cutting time from thread length, approach length, and feed rate.

Calculates required thread engagement from axial force, allowable shear stress, and effective shear perimeter.
