IMPA 690501 HEX.SOCKET HEAD CAP SCREW M3x30 DIN 912-STEEL 8.8

Hex socket head cap screws are commonly used in machine assembly, especially forboroed bosses, in order to keep them flush with the surface. They are also used in many other engineering applications. The main feature of these screws is the hexagonal socket drive type, which is used to drive the screw into place using a wrench or socket. The head is usually counter-sunk so that it is flush with the surface when installed. These screws are made of steel which gives them extra strength and durability.
