Terms of Service & Disclaimer
Last Updated: September 13, 2026 • Effective Date: September 13, 2026
Crucial Engineering & Manufacturing Disclaimer
All calculations, pitch diameter limits, crest/root geometry diagrams, formulas, tap drill charts, and SolidWorks CAD profile files (.SLDLFP) provided on Fasteners Standards are designed for engineering evaluation, academic reference, and drafting convenience. While every effort is made to conform strictly to ISO 261, ISO 965, ASME B1.1, ASME B1.5, and ASME B1.8, you must independently verify all critical dimensions against official standard documentation before commencing physical CNC machining, tooling fabrication, aerospace manufacturing, or structural assembly. Fasteners Standards assumes no legal or financial liability for broken tooling, scrapped workpieces, machining discrepancies, or mechanical failures.
