Thread standards. Tapping tools are manufactured in five different standards: ISO, ANSI, DIN, DIN/ANSI, and JIS. DIN and ISO are common worldwide, ANSI is most common in American markets and JIS is most common in Asia markets.
ISO 965 consists of the following parts, under the general title ISO general purpose metric screw threads — Tolerances: — Part 1: Principles and basic data. — Part 2: Limits of sizes for general purpose external and internal screw threads — Medium quality. — Part 3: Deviations for constructional screw threads.
The limiting sizes for standard threads given in the table comply with - tolerance field 6g for bolt threads - tolerance field 6H for nut threads. The metric steel and metal threads specified in this catalogue are based on the tolerance fields given above.
