### 1/5 — Fake App

*2021-08-26*

Calculation results are totally wrong.

### 1/5 — R2 measurement incorrect

*2021-06-16*

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.

## Frequently asked questions about Screw Flight Pro

### What is Screw Flight Pro used for?

Screw 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.

### What information do I need to input into Screw Flight Pro?

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.

### What kind of output does Screw Flight Pro provide?

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.

### Can Screw Flight Pro calculate the weight of the flight?

Yes, you can select the specific gravity from a dropdown list to calculate the weight of the flight, which is useful for material estimation.

### What materials can be used with Screw Flight Pro?

The app supports calculations for various construction materials, including carbon steel, stainless steel, copper, brass, or bronze.

### Is Screw Flight Pro suitable for other fabrication projects besides screw conveyors?

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.

### What is the price of Screw Flight Pro?

Screw Flight Pro is a paid application, available for $3.99.
