About the Screw M2x8, Stainless Steel A2, ISO 10642
This Screw M2x8 Stainless Steel A2 ISO 10642 item follows the countersunk flat-head hexagon socket screw pattern of ISO 10642 (the DIN 7991 equivalent): a 90-degree conical head with an internal hex drive that pulls fully flush into a matching countersunk seat, leaving no protrusion above the surface. It carries a fine-scale M2 x 0.4 coarse metric thread over an 8 mm nominal length, placing it among the smallest countersunk socket screws in regular industrial use. The hex socket gives controlled tightening at a size where slotted drives cam out easily, and the flush head suits sliding surfaces, covers and close-fitting assemblies where any head height would foul adjacent parts. The material is A2 austenitic stainless steel (304 type), resisting atmospheric corrosion without plating — important at this scale, where coating thickness can interfere with thread fit. Typical drive size for M2 countersunk socket screws is a 1.3 mm hex key.
