Metric DIN 963 Slotted Flat Countersunk Head Machine Screws Specification pdf
Metric DIN 963 are slotted drive flat countersunk head machine screws. Metric machine screws are designed for metal to metal applications requiring a pre-drilled hole and a mating metric nut for the screw to thread into. These screws are usually fully threaded with machine threads and blunt point. The recommended pre-drilled hole sizes vary depending on the diameter of the screw to be used but should be slightly larger in diameter than the major (maximum) thread diameter. These screws are available in zinc plated steel as well as stainless steel A2 and A4. Metric flat countersunk heads have a flat top surface and a cone-shaped bearing surface with a head angle of approximately 90°. They are used for applications where the head must be flush with the mating surface of the substrate.
