Fasteners - Button head screws with reduced loadability - Part 2: Hexagon socket button head screws with collar (ISO 7380-2:2022)
SIST EN ISO 7380-2:2023

This document specifies the characteristics of hexagon socket button head screws with collar, with reduced loadability due to head design, in steel, with metric coarse pitch threads M3 to M16, and with product grade A.
If in certain cases other specifications are requested, dimensional options can be selected from ISO 888 or ISO 4753.
NOTE      The reduced loadability (related to the head dimensions in combination with penetration of the hexagon socket specified in this document) implies a limitation of ultimate tensile load shown by a specific marking (property class preceded by a zero). The loadability in the head is assumed to be 80 % of that in the thread for all sizes and all property classes, see Table 4.

SIST EN ISO 14581:2023

This document specifies the characteristics of hexalobular socket countersunk flat head screws with reduced loadability due to head design, in steel and stainless steel, with metric coarse pitch threads M2 to M10, and with product grade A.
If in certain cases other specifications are requested, stainless steel grades can be selected from ISO 3506‑1, and dimensional options from ISO 888 or ISO 4753.
NOTE 1   The reduced loadability (related to the countersunk head dimensions in combination with penetration of the hexalobular socket specified in this document) implies a limitation of ultimate tensile load shown by a specific marking (property class preceded by a zero). The loadability in the head is assumed to be 80 % of that in the thread for all sizes and all property classes; see Table 3.
NOTE 2   Hexalobular socket countersunk head screws (high head), with full loadability are specified in ISO 14582, but these products are not interchangeable, because of different head heights.
NOTE 3   Particular attention is needed to ensure alignment of the countersunk head with the bearing surface of the countersink in the assembly.

Fasteners - Heat treated tapping screws - Mechanical and physical properties (ISO 2702:2022)
SIST EN ISO 2702:2023

This document specifies the mechanical and physical properties of heat treated tapping screws made of steel, with thread sizes ST2,2 to ST9,5 in accordance with ISO 1478, when tested at the ambient temperature range of 10 °C to 35 °C, and the related test methods.
Tapping screws are designed to form mating threads in sheet metals, without their own threads being deformed. Tapping screws are not intended to be pretensioned by design, even though they can experience varying degrees of low-level tensile stress after installation.
