Overview
ISO 8749:1986 - Pins and grooved pins - Shear test defines a standardized test method for determining the shear resistance of metallic pins and grooved (elastic) pins with nominal diameters from 0.8 mm to 25 mm inclusive. The standard specifies the test principle, a typical test fixture, specimen mounting, test speed, and acceptance observations so results are repeatable and comparable across laboratories and manufacturers.
Key topics and requirements
- Scope: Metallic pins and grooved (cannelée / elastic) pins, nominal diameter 0.8–25 mm.
- Test principle: Apply a shear load (typically double shear fixture) and record the maximum load at rupture - this is the pin’s double-shear resistance.
- Fixture details:
- Typical test fixture (figure provided) with support blocks and load block drilled for the pin nominal diameter (hole tolerance H6).
- Mounting sleeves and shear blocks are hardened; block hardness must be at least 700 HV.
- Clearance (play) between support block and load block must not exceed 0.15 mm.
- Shear plane geometry:
- Each shear plane located at least one pin diameter from the corresponding pin end.
- Distance between the two shear planes must be at least two times the pin diameter.
- Pins too short for double shear are tested in pairs in single shear, loaded simultaneously.
- Special mounting: Elastic (grooved) pins are mounted with the slot facing upwards in the fixture.
- Test procedure and acceptance:
- Pins are tested to rupture; the maximum applied load at rupture (or just before) is reported as shear strength.
- Pins should display ductile shear without longitudinal cracking.
- Test crosshead speed must not exceed 13 mm/min.
Applications and users
ISO 8749:1986 is used to:
- Verify mechanical performance and quality of pins and grooved pins in manufacturing QA/QC.
- Provide comparative shear strength data for design and material selection (mechanical engineers, design engineers).
- Support procurement specifications and acceptance testing for fasteners in automotive, aerospace, machinery and general engineering.
- Standardize test reporting in independent test laboratories and certification bodies.
Typical users: fastener manufacturers, test laboratories, quality engineers, design and R&D teams, and standards/inspection authorities.

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. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take patt in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 8749 was prepared by Technical Committee ISO/TC 2,
Fas teners.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
Jatest edition, unless othetwise stated.
