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