Fasteners - Taper grooved pins - Full-length progressive grooves

This document specifies the characteristics of taper grooved pins with full-length progressive grooves (with closed end at the insertion side), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm.These grooved pins are designed to fulfil the main following function: locking together two or more parts, with an easy installation (due to its shape) and a high level of pull-out resistance (due to the elastic fit behaviour of the pin).The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

La présente Norme internationale prescrit les caractéristiques des goupilles cannelées en acier ou en acier inoxydable austénitique, à trois cannelures progressives sur toute leur longueur, débouchantes d'un côté et régulièrement espacées, de diamètre nominal, d1, de 1,5 mm à 25 mm inclus. Le matériau refoulé de chaque côté des cannelures forme un renflement dont le diamètre d2, supérieur au diamètre nominal d1, permet un ajustement serré de ces goupilles cannelées lorsqu'elles sont emmanchées en force dans un trou de diamètre de perçage égal au diamètre nominal de la goupille d1 (voir article 4).

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
