Overview
ISO 2338:1997 defines the characteristics and designation of parallel pins (also called cylindrical or straight pins) made from unhardened steel and austenitic stainless steel. The standard covers nominal diameters from 0.6 mm to 50 mm, specifies dimensional tolerances and commercial lengths, and gives requirements for material, surface finish, hardness and workmanship. ISO 2338 is a fasteners standard intended for manufacturers, designers and quality inspectors who need consistent, interchangeable pins for precision assembly and tooling.
Key Topics
- Size range and dimensions: Nominal diameters d = 0.6 mm to 50 mm; standard nominal lengths listed with acceptable min/max tolerances and commercial length steps (above 200 mm in 20 mm increments).
- Tolerance classes: Typical tolerance classes referenced are m6 and h8; tolerances apply before any plating or coating.
- Material and hardness:
- Unhardened steel (St): hardness specified in the standard (given as HV30 range).
- Austenitic stainless steel (A1): material grade referred to ISO 3506-1 with its own hardness range.
- Surface finish and coatings:
- Steel pins: plain (natural) finish or treated finishes such as black oxide, phosphate coating or zinc plating with chromate conversion; pins often supplied with protective lubricant unless otherwise agreed.
- Austenitic stainless steel: normally supplied plain (natural finish).
- Surface roughness:
- For m6 tolerance class: R < 0.8 µm
- For h8 tolerance class: R < 1.6 µm
- Workmanship and acceptability:
- Pins must be free from irregularities, detrimental defects and burrs.
- Acceptance inspection follows ISO 3269.
Applications
ISO 2338 parallel pins are widely used for:
- Alignment and location in assemblies (dowels and locating pins)
- Fixtures, jigs and tooling for machining and production
- Precision mechanical assemblies in automotive, machinery, electronics and other industrial equipment
- Replacement parts and procurement where interchangeability and conformity to standards are required
Who uses it:
- Fastener and precision pin manufacturers
- Mechanical designers and engineers specifying dowel/pin dimensions and tolerances
- Procurement and quality control personnel enforcing acceptance inspection criteria

- ISO 3506-1 - Mechanical properties of corrosion‑resistant stainless steel fasteners (referenced for austenitic grades)
- ISO 4042 - Fasteners: Electroplated coatings (referenced)

Designation example from ISO 2338:
- Parallel pin ISO 2338 – 6 m6 × 30 – St (steel)
- Parallel pin ISO 2338 – 6 m6 × 30 – A1 (austenitic stainless steel)

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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 2338 was prepared by Technical Committee
ISO/TC 2, Fasteners.
This second edition cancels and replaces the first edition (ISO 2338:1986),
which has been technically revised.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération
mondiale d'organismes nationaux de normalisation (comités membres de
l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l'ISO participent également aux travaux. L'ISO collabore
étroitement avec la Commission électrotechnique internationale (CEI) en
ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l'approbation de 75 % au moins des
comités membres votants.
La Norme internationale ISO 2338 a été élaborée par le comité technique
ISO/TC 2, Éléments de fixation.
Cette deuxième édition annule et remplace la première édition
(ISO 2338:1986), dont elle constitue une révision technique.
