Overview

EN ISO 2338:1997 (ISO 2338:1997) specifies the characteristics, dimensions and basic requirements for parallel pins (cylindrical pins) made of unhardened steel and austenitic stainless steel. The standard covers nominal diameters from 0.6 mm to 50 mm and a commercially used series of nominal lengths. It is a product standard widely used by designers, manufacturers and purchasers of fasteners and locating elements.

Key topics and technical requirements

• Scope and sizes
  • Nominal diameters d = 0.6 mm to 50 mm inclusive.
  • Nominal lengths provided in a standard series (table of lengths up to and beyond 200 mm; above 200 mm lengths in 20 mm steps).
• Tolerances and fit
  • Typical tolerance classes referenced: m6 and h8. Dimensional tolerances are specified in the standard’s tables.
  • All dimensional tolerances apply prior to plating or coating.
• Material and hardness
  • Unhardened steel (St): hardness range 125 HV30 to 245 HV30.
  • Austenitic stainless steel (grade A1): hardness range 210 HV30 to 280 HV30, with mechanical properties referenced to ISO 3506-1.
• Surface finish and coatings
  • Pins are normally supplied plain (natural finish) or, by agreement, with coatings.
  • Preferred coatings for steel pins: black oxide, phosphate, or zinc plating with chromate conversion (see ISO 9717 and ISO 4042).
  • Surface roughness targets: for m6 R < 0.8 µm, for h8 R < 1.6 µm.
• Workmanship and acceptance
  • Pins must be free of irregularities and burrs.
  • Acceptance inspection procedures follow ISO 3269.

Applications and users

• Practical uses:
  • Locating, aligning and securing machine components, jigs and fixtures.
  • Assembly and repair work where precision dowel or locating pins are required.
• Primary users:
  • Mechanical designers and engineers specifying fasteners and locating elements.
  • Fastener manufacturers, quality inspectors and purchasing/procurement teams.
  • Maintenance and assembly technicians in industries such as general machinery, tooling, automotive and other manufacturing sectors.

Related standards

• ISO 3269 - Fasteners: Acceptance inspection
• ISO 3506-1 - Mechanical properties of corrosion-resistant stainless steel fasteners
• ISO 4042 - Fasteners: Electroplated coatings (revision referenced)
• ISO 9717 - Phosphate conversion coatings for metals

Example designation formats in the standard:

• Parallel pin ISO 2338 – 6 m6 × 30 – St (unhardened 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.
