ISO14581 Hexalobular Socket Countersunk Flat Head Screws

ISO 14581 Hexalobular Socket Countersunk Flat Head Screws are designed for applications where a flush surface finish, reliable fastening, and efficient assembly are required. The countersunk flat head allows the screw to sit level with the material surface after installation, reducing protrusion and providing a clean appearance for finished assemblies.

The hexalobular socket drive provides secure tool engagement and stable torque transmission during tightening, helping reduce the risk of recess damage in production environments. Manufactured according to ISO 14581 requirements, these screws are available in stainless steel, carbon steel, and alloy steel with various strength grades and surface finishes. They are suitable for precision machinery, equipment manufacturing, electronic products, and assemblies where a smooth surface and space-efficient fastening solution are important.

Specification:

The specification of ISO 14581 Hexalobular Socket Countersunk Flat Head Screws is mainly defined by the relationship between the countersunk head geometry, drive system, and thread dimensions. The countersunk head angle and head diameter are critical factors to ensure the screw sits correctly below or flush with the mating surface, while the hexalobular recess dimensions determine proper tool engagement during installation.

Available specifications include metric thread sizes, different screw lengths, material options, and mechanical grades to meet various fastening requirements. These screws can be supplied in stainless steel for corrosion-resistant applications, carbon steel for general industrial use, and alloy steel where higher mechanical strength is required. Surface treatments and finishes can also be customized according to operating conditions and customer requirements.

Dimension Chart of ISO14581 Stainless Steel Hexalobular Socket Countersunk Flat Head Screws:

The dimension chart of ISO 14581 Hexalobular Socket Countersunk Flat Head Screws provides detailed information about the geometry of the countersunk head and fastening dimensions defined by the standard. Key dimensions include thread diameter, screw length, head diameter, countersunk head angle, head height, and hexalobular recess size.

The correct combination of head dimensions and countersink geometry ensures that the screw can be properly seated into the mating component to achieve a flush installation surface. During production, critical dimensions such as head profile, recess depth, and thread accuracy are inspected to maintain compatibility with standard assembly requirements. Customized dimensions are also available according to customer drawings or specific application requirements.
