Fasteners — Reverse-taper grooved pins — Half-length progressive grooves

This document specifies the characteristics of reverse-taper grooved pins with half-length progressive grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm.These grooved pins are designed to fulfil the main following functions:—     positioning or guiding, and—     relative rotation of the assembled parts,with an easy installation (due to its shape) and a medium 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.

Fasteners — Reverse-taper grooved pins — Half-length progressive grooves

This document specifies the characteristics of reverse-taper grooved pins with half-length progressive grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm.

These grooved pins are designed to fulfil the main following functions:

     positioning or guiding, and

     relative rotation of the assembled parts,

with an easy installation (due to its shape) and a medium 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.

Grooved pins. Half-length reverse-taper grooved.

La présente Norme internationale prescrit les caractéristiques des goupilles cannelées en acier ou en acier inoxydable austénitique, à trois cannelures progressives renversées sur la moitié de leur longueur, non débouchantes 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).
