NOTE

Limited Use:
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 Seating Torque

Property Class 10.9
Hardness (HRC) 32-39
Tensile Strength (Mpa) 835 min.
