ISO 7380 Hexagon Socket Button Head Screws Class 10.9 Black
ISO 7380 - Hexagon Socket Button Head Screws Class 10.9 Black
Socket button head cap screws ISO 7380 are not intended for high strength application. The purpose of producing them with a strength of the property class 10.9 is to increase the wear resistance of the sockets.
ISO 7380 : 2004 Hexagon socket button head screws,which was prepared by ISO/TC 2 ‘Fasteners’ of the International Organization for
Standardization, has beenadopted by Technical Committee CEN/TC 185 ‘Threaded and non-threaded mechanical fasteners andaccessories’, the
Secretariat of which is held by DIN, as a European Standard.

Stainless steels can be divided into three groups of steel - austenitic. ferritic and martensitic. Austenitic steel is by far the
mostcommon type (>90% of commercial fasteners). The steel groups and strength classes are designated by a four-digit
sequenceof letters and numbers (eg A2-70) as shown in the following table. DIN EN ISO 3506 governs screws and nuts made
fromstainless steel.
