Stainless Steel Socket Countersunk Screws - ISO 10642 - CB10 Our stainless steel socket countersunk screw are manufactured from A2 stainless steel (304) to the specification ISO 10642. The flat 90° countersunk head sits perfectly flush with the surface when installed into a pre-drilled countersunk recess, giving a completely clean, snag-free finish. The Flush Fit Advantage The defining characteristic of a countersunk screw is its ability to sit level with or below the surface of the parent material, eliminating any protruding head. This makes ISO 10642 countersunk screws the natural choice wherever a smooth, uninterrupted surface is essential - from precision instrument panels and electronic enclosures to motorcycle bodywork, automotive trim and architectural metalwork. The internal hex (allen key) socket drive keeps the head profile minimal and allows installation in recessed or restricted-access locations where a standard driver can't be reached. Typical Uses Motorcycle fairings and bodywork, automotive interior and exterior trim, precision instrument panels, electronic equipment enclosures, architectural and decorative metalwork, furniture hardware, marine fittings and any application requiring a flush, corrosion-resistant fixing.
