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.
Abstract
Overview
ISO 8741:2025 specifies the characteristics of reverse‑taper grooved pins - half‑length progressive grooves (closed ends) manufactured in steel and stainless steel, with nominal diameters from 1 mm to 25 mm. These grooved pins are intended for positioning/guiding and for enabling relative rotation of assembled parts. The design provides easy installation (reverse‑taper shape) and a medium level of pull‑out resistance through elastic fit behaviour. General functional principles and common requirements for grooved pins and assembly are given in ISO 13669.
Key topics and requirements
- Geometry and dimensions: detailed dimensions and standard length ranges for nominal diameters 1–25 mm; groove length is specified as l/2 with defined tolerances depending on pin length.
- Groove location: grooves must remain closed at the ends; the start of grooves must be positioned within lmax limits that depend on overall length (e.g., l ≤ 10 mm → lmax = 1 mm; 10
