ISO10642 Socket Cap Countersunk Head Screws
ISO 10642 Socket Cap Countersunk Head Screws are precision fastening components featuring a countersunk flat head design and internal hexagon socket drive. Manufactured according to ISO 10642 specifications, these screws allow the head to sit flush with or below the surface of the assembled material, providing a smooth appearance and preventing interference in applications where space and surface finish are important.
With their angled countersunk head and hex socket drive, ISO 10642 screws provide reliable clamping performance and easy installation using standard hex keys. They are available in stainless steel, alloy steel and other materials with different strength grades and surface finishes, making them suitable for applications requiring secure fastening, clean appearance and accurate assembly.
