The Intel NUC6i7KYB uses M.2 mounting screws for securing M.2 SSDs and other internal components. These are typically M2 x 3mm or M2 x 4mm screws, depending on the specific slot or bracket design.
For the chassis and case assembly, standard Phillips-head screws (approximately M2.5) are often used. Always refer to the Intel NUC6i7KYB Technical Product Specification or user manual for exact details
