ISO 7380-2 - 2011 Hexagon Socket Button Head Screws With Collar

         QBH Socket head cap screws are commonly used in machine assembly for removable panels and parts. They have a round cap with a hex head and are tightened with a socket wrench drive.Longer caps are easier to see when fastened, while button and flat head caps are less likely to snag clothing or linkages. Cap screws with a black oxide or armor coat finish resist corrosion.

        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

       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.
