This standard BS EN ISO 8744:2025 - TC Tracked Changes. Fasteners. Taper grooved pins. Full-length progressive grooves is classified in these ICS categories:
21.060.50 Pins, nails
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.
