Thread Stripping Strength vs Circle Coordinate Calculator Utilisation & Stats

With a few parameters (diameter, pitch, thread tolerances, quality class and engaged thread length) the application automatically calculates the minimum failure load (stripping) of the bolt threads and the threads of the tap. Except in special cases, these two values must be greater than the failure load of the bolt. The application includes metric thread databases (coarse, fine or custom pitch), carbon steel (ISO 898-1) and stainless steel (ISO 3506-1) property classes, and thread tolerance positions a to h for bolts and G to H for taps, with their associated manufacturing quality (µm) in accordance with ISO 965-1. The application also enables you to check that the pairing chosen is recommended and that the diametral overlap of the threads is sufficient. After calculation, the calculated data can be exported in .CSV format and sent by message or email (for import into an Excel spreadsheet, for example). The calculation is performed according to the formulas proposed in standard NF E 25030-2, with tolerances.
