Overview

This document covers the draft international standard ISO/DIS 10513:2016 - Prevailing torque (all-metal) hexagon high nuts, with fine pitch thread (designation often shortened to PTAM). It specifies dimensions, functional properties and product grades for all-metal prevailing-torque hexagon high nuts with fine pitch metric threads, nominal diameters M8 to M39, and two product grades: A (D ≤ 16 mm) and B (D > 16 mm). Note: according to the provided scope metadata the project was cancelled in ISO/CS on 2017-11-17; the content below describes the draft technical requirements as circulated.

Key Topics and Requirements

• Product scope: All‑metal prevailing torque hexagon high nuts (PTAM) with fine pitch metric threads M8×1 through M39×3 (preferred and non-preferred thread tables are included).
• Dimensions & geometry: Detailed dimension tables and a figure define height, width across flats, thread allowances and prevailing‑torque element geometry (manufacturer may choose shape).
• Product grades: Grade A for nominal diameters ≤16 mm; Grade B for >16 mm.
• Materials & property classes:
  • Steel: property classes 8, 10, 12 (quenching and tempering requirements referenced to ISO 898-2; class 12 extended to whole diameter range in the draft).
  • Stainless steel: classes per ISO 3506-2 (examples in draft: A2‑70, A4‑70, A4‑80).
• Threads & tolerances: Metric fine pitch threads per ISO 262 / ISO 724 with tolerance class 6H for internal threads and ISO 965-2 for limits.
• Functional testing & acceptance: Prevailing torque and functional properties referenced to ISO 2320; acceptance inspection per ISO 3269.
• Surface finish & coatings: Electroplating (ISO 4042), zinc‑flake (ISO 10683), passivation for stainless steel (ISO 16048); surface discontinuities per ISO 6157-2.
• Designation example: PTAM hexagon high nut ISO 10513 – M12 × 1.5 – 8

Applications and Users

• Applications: Used where a secure threaded joint must resist rotation under vibration or thermal cycling - automotive, rail, heavy machinery, aerospace subassemblies, precision equipment using fine‑pitch threads.
• Who uses it:
  • Fastener manufacturers and product engineers specifying PTAM nuts.
  • Design and mechanical engineers selecting fasteners for vibration‑resistant joints.
  • Quality, inspection and procurement teams enforcing acceptance and coating requirements.
  • Test laboratories performing prevailing‑torque and mechanical property verification.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further ma intenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

The committee responsible for this document is ISO/TC 2, Fasteners, Subcommittee SC 12, Fasteners
with metric internal thread.
This third edition cancels and replaces the second edition (ISO 10513:2012).
This standard differs from ISO 10513:2012 as follows:
— the Scope has been updated;
— the preferred and the non-preferred threads are given in two separate tables, and the threads
M181,5, M221,5, M27, M33 and M393 have been added;
— threads M10x1,25 and M20x2 have been moved to the preferred threads table;
— h have been amended for M12 (12,60 instead of 12,30) and M24 (24,00 instead of 23,90);
,max
— for steel nuts, the property class 12 has been extended to the whole diameter range;
— for steel nuts, quenching and tempering have been specified in accordance with ISO 898-2 as
mandatory or optional;
— the reference to ISO/TR 16224 for nut design has been added;
— stainless steel nuts have been added;
— "prevailing torque all-metal" has been replaced by the symbol "PTAM" in the designation.
