Fake App
Calculation results are totally wrong.
R2 measurement incorrect
R2 measurement is marked as radius but is the diameter. R1 is the radius. Also would be better if I could change the measurement to inches.

Calculate screw flight development for fabrication. This app provides flat pattern sizes for cutting blank plates, essential for screw conveyors and ribbon blenders. It helps determine raw cutting plate dimensions for various process equipment.

MoreScrew Flight Pro is designed for calculating screw flight development, providing flat pattern sizes needed for fabricating screw flights. This is crucial for manufacturing screw conveyors, ribbon blenders, and other process equipment.
You need to input the outside and inside diameter of the screw, the pitch of the flight, the material thickness, and the specific gravity of the construction material.
The app provides the development outside diameter and inside diameter of the raw plate circle. This allows for a perfect fit with the shaft or pipe after the plate is twisted.
Yes, you can select the specific gravity from a dropdown list to calculate the weight of the flight, which is useful for material estimation.
The app supports calculations for various construction materials, including carbon steel, stainless steel, copper, brass, or bronze.
Yes, the app is also beneficial for those fabricating pressure vessels, heat exchangers, storage tanks, agitators, mixers, and any other process equipment that requires precise component development.
Screw Flight Pro is a paid application, available for $3.99.
The latest version, 2.0, was released on April 22, 2023, indicating regular updates to improve functionality and compatibility.
