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.
Tightening Procedure:
Insert the key into the socket and apply the torque on the nut while holding the key. Should however, the torque be applied on the screw itself it should be reduced accordingly.
R.S. Torque = Recommended SeatingTorque
l - length of bolt
d - the nominal diameter of the thread
k - head height
dk - head diameter
s - size of the internal hexagon
Steel: 8.8,10.9,12.9
Stainless: A2, A4
Plastic: -
Non Ferrous: -
Thread: 6g, 5g6g for strength 12.9

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.
