Overview
ISO 8735:1997 specifies requirements for parallel (cylindrical) pins with internal thread, made of hardened steel and martensitic stainless steel. The standard covers nominal diameters from 6 mm to 50 mm and defines two main types: Type A (through‑hardened, with crown) and Type B (flat, case‑hardened). It provides dimensions, material and hardness requirements, surface finish and quality criteria, and example designation formats.
Key topics and technical requirements
- Diameter and length range: nominal diameters d = 6–50 mm; common nominal lengths listed (16 mm up to 200 mm and beyond in 20 mm steps).
- Types:
- Type A: pins through‑hardened (also available in martensitic stainless steel C1).
- Type B: case‑hardened (cemented) steel pins.
- Materials and composition: the standard gives compositional limits for the steels and the martensitic stainless variant (C1) and permits other materials by agreement.
- Hardness:
- Through‑hardened pins: specified bulk and surface hardness ranges (e.g., 550–650 HV30 surface range referenced in the standard).
- Case‑hardened pins: surface hardness and case depth requirements (minimum case hardness and typical case thickness specified).
- Thread and tolerances: internal threads follow metric ISO tolerances (metric threads, tolerance grade 6H per ISO 965‑2). Thread pitches and matching nominal thread sizes (M4–M24 depending on pin diameter) are listed.
- Surface quality and finish: surface roughness and absence of harmful defects required; coatings are permitted but must address hydrogen embrittlement risks and follow suitable post‑treatment (see ISO 4042).
- Inspection and acceptance: reception and inspection procedures reference ISO 3269.
- Designation examples: e.g., “Goupille cylindrique ISO 8735 – 6·30 – A – St” (hardened steel, 6×30 mm, Type A) or “Goupille cylindrique ISO 8735 – 6·30 – C1” (martensitic stainless C1).
Applications and users
- Typical applications: precise locating, alignment and load‑bearing dowel/pin applications in machinery, tooling, automotive assemblies, and precision equipment where controlled fit, strength and corrosion resistance are required.
- Who uses this standard:
- Mechanical designers and engineers specifying pins for assemblies
- Fastener and component manufacturers producing to ISO dimensions and hardness
- Quality assurance and inspection teams verifying acceptance criteria
- Procurement and supply chain professionals sourcing standardized pins

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 8735 was prepared by Technical Committee
ISO/TC 2, Fasteners.
This second edition cancels and replaces the first edition (ISO 8735:1987),
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 8735 a été élaborée par le comité technique
ISO/TC 2, Éléments de fixation.
Cette deuxième édition annule et remplace la première édition
(ISO 8735:1987), dont elle constitue une révision technique.
