Screw Flight Calc

Screw Flight Calculator is a professional fabrication tool designed to calculate flat pattern development and weight of screw conveyor flights. The app is built for fabricators, engineers, conveyor manufacturers, and workshop professionals who need fast and accurate results without manual calculations or spreadsheets.

This application supports both Metric and Imperial units with automatic internal unit conversion, making it ideal for shop-floor fabrication work.

Screw Flight Development:
The app calculates flat pattern dimensions for screw flights with and without radial cuts. Users can switch between radial cut and full ring layout modes based on their fabrication method.

Accurate Geometry Output:
The calculator automatically determines:

Flight width

Inner and outer radii

Cut angles (alpha and beta)

Developed lengths (X1, X2, A1, A2)

Weight Estimation:
The app provides instant weight per flight piece based on material thickness and material density, helping estimate material usage and fabrication cost.

Engineer-Friendly Inputs:

Screw flight outer diameter

Pipe or shaft diameter

Pitch

Thickness

Material density

Smart Unit Handling:

Metric and Imperial unit support

mm and inch input

Automatic unit conversion

Clear and workshop-ready output format
