Code Structure

Thread Designation Decoder splits the marking into recognized segments, explains what each segment means, and flags ambiguous or incomplete inputs.

How To Decode

  1. Enter the marking exactly as printed, including spaces, hyphens, suffixes, and units.
  2. Review the segment breakdown first, then compare candidates in the result table when more than one interpretation is possible.
  3. Use the cited standard or manufacturer datasheet before making safety, procurement, or compliance decisions.

Decode logic

  • Normalize the marking, parse the known tokens, then return the decoded meaning with confidence and source caveats.

FAQs

Can this decoder guarantee the final specification?

Thread Designation Decoder explains the visible marking and highlights common meanings. Always confirm safety-critical or purchase decisions against the manufacturer data sheet, product label, and applicable local standard.

Why can one code have more than one meaning?

Many real-world markings are reused by different manufacturers, regions, packages, or standard systems. Use surrounding context such as package, size, voltage, country, and product family.

What is a good input example?

Use the complete visible marking, for example M10x1.5-6g, including spaces, suffixes, and ratings when they are printed on the part.
