About the Hex Socket Cap Head Screw M3x25
This screw hex socket cap head item is an M3 x 25 mm cap screw in A2 stainless steel, threaded along its entire 25 mm length. The thread is M3 with the 0.5 mm coarse pitch, and the head is the cylindrical cap form driven by an internal hexagon key rather than a spanner or a cross recess. A4 grades are specified where chlorides are present; A2 is the chromium-nickel austenitic grade used for general corrosion resistance indoors and in sheltered positions. Because the screw is fully threaded rather than partially threaded, the thread continues right up to the underside of the head, so grip length is set entirely by the stack of parts and washers. The governing dimensional standard is not stated on the part record; confirm it, and any certification you require, at enquiry stage.

Typical applications
A general-purpose M3 fixing for assemblies where the 25 mm length must span a cover, a spacer or a pair of plates before entering a tapped hole or reaching a nut. Full threading suits adjustable stacks, since washers or shims can be added or removed without leaving an unthreaded shank in the engagement zone. The socket head allows tightening in recesses where there is no room to swing a spanner.
