IMPA 690501 HEX.SOCKET HEAD CAP SCREW M8x40 DIN 912-ST.STEEL A2

The IMPA 690501 HEX.SOCKET HEAD CAP SCREW M8x40 DIN 912-ST.STEEL A2 is a type of fastener, specifically a hex socket head cap screw, that is used to join two or more pieces of material together. The screw is made of steel, is 8mm in diameter, and is 40mm long. It has a hexagonal socket head, which allows it to be turned with a wrench, and is threaded so that it can screw into a nut or tapped hole. The head of the screw is also counter-sunk, meaning that it sits flush with the surface of the material it is being used to fasten. This particular screw is also zinc plated, which gives it some corrosion resistance.
