BS EN ISO 8741:2025 - TC

This standard BS EN ISO 8741:2025 - TC Tracked Changes. Fasteners. Reverse-taper grooved pins. Half-length progressive grooves is classified in these ICS categories:

• 21.060.50 Pins, nails

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.
