Fasteners — Button head screws with reduced loadability — Part 2: Hexagon socket button head screws with collar

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.
