This standard specifies the characteristics of cross-recessed countersunk flat head tapping screws with thread sizes from ST 2,2 to ST 9,5 inclusive. With respect to the previous edition, in addition to the editorial revision, the specifications regarding the finish have been concretised by supplementing non-electrolytically applied zinc flake coatings and passivation, and new materials and an additional thread end form have been added. This document (EN ISO 7050:2011) has been prepared by Technical Committee ISO/TC 2 "Fasteners", in collaboration with Technical Committee CEN/TC 185 "Fasteners" (secretariat: DIN, Germany). The responsible German committee is Working Committee NA 067-00-05 AA "Kleinschrauben und gewindeformende Schrauben" ("Miniature screws and thread forming screws") of the Fasteners Standards Committee (FMV).
This document replaces DIN ISO 7050:1990-08 .
