| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Approving a named sample without accidentally approving bulk | Checking GOTS certification records |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | The record does not validate every size or user, prove bulk conformity, prescribe universal defect classes or AQL, replace testing or inspection, or establish compliance. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. |

| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | The record applies version and lot controls from textile testing plus current ISO and ASQ acceptance-sampling boundaries to separate sample approval from bulk release. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. |
