This document specifies the characteristics of taper grooved pins with half-length progressive grooves (with close-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 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 8745:2025 - Fasteners - Taper grooved pins - Half-length progressive grooves specifies the characteristics, dimensions and marking of taper grooved pins with half‑length progressive grooves (close‑end at the insertion side). The standard covers pins manufactured in steel and stainless steel, with nominal diameters from 1 mm to 25 mm, intended for positioning/guiding and enabling relative rotation of assembled parts. General functional requirements and assembly principles are referenced to ISO 13669.
Keywords: ISO 8745:2025, taper grooved pins, half-length progressive grooves, fasteners, steel, stainless steel, expanded diameter.
Key topics and requirements
- Scope and function: Pins designed for easy installation and medium pull‑out resistance due to elastic fit; primary functions are positioning/guiding and permitting relative rotation.
- Materials: Steel (symbol St) and stainless steel grades (A1, A2, A4, C1, F1); other materials (e.g., hardened steels, brass, aluminium) allowed by agreement when mechanical/physical properties are defined.
- Dimensions and geometry:
- Nominal diameter range: 1 mm to 25 mm.
- Grooves: three grooves, open at the non‑insertion end; groove spacing angle 120° ±20°; groove angle ~70° (reference).
- Groove length equals l/2 with tolerances:
- l ≤ 10 mm: ±0.3 mm
- 10 mm
