This standard BS EN ISO 8747:2025 - TC Tracked Changes. Fasteners. Grooved pins with countersunk head. Full-length diamond grooves is classified in these ICS categories:
21.060.50 Pins, nails
This document specifies the characteristics of grooved pins with countersunk head and full-length diamond grooves and pilot or chamfer point, in steel and stainless steel, and with nominal diameter 2 mm to 20 mm. These grooved pins are designed to fulfil the main following function: locking together two or more parts, with the easiest installation (due to the pilot or chamfer point) and a highest 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.
