Metric ISO 7380 Button Head Hexagon Socket Cap Screw BLACK 8.8 10.9
Metric ISO 7380 Button Head Hexagon Socket Cap Screws have a button head head with an internal hexagonal drive suited
for a hex / Allen key or wrench. ISO 7380-2 offers a additional collar/flange that increases the head diameter thereby
increasing the weight bearing surface area. The internal drive is ideal for situations where externally wrenched screws are
impractical such as in applications where limited space is available.
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.
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.
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
