ISO 8744 - Grooved Pins, Full Length Taper-grooved Current norm: DIN EN 28744 Equivalent norms: DIN 1471; CSN 022170; PN 85025; EU 28744;

?terms and definitions, principles for grooved pins and assembly (including hole dimensions), control of the expanded diameter d 2 and pin straightness, mechanical and physical properties (including shear resistance and hardness) and inspection which are common for all grooved pins (product standards ISO 8739 to ISO 8747, ISO 13670 and ISO 13672) have ...

These grooved pins are designed to fulfil the main following function: with an easy installation (due to its shape) and a high level of pull-out resistance (due to the elastic fit behavior of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.
