ISO14584 Torx Raised Countersunk Head Screws
ISO 14584 Torx Raised Countersunk Head Screws combine a raised countersunk head profile with a hexalobular (Torx) drive, providing a practical fastening solution where controlled head projection and reliable tool engagement are required. The raised countersunk head creates a smooth transition between the screw head and the mating surface, offering a different seating profile from fully flat countersunk screws while maintaining a relatively low-profile appearance.
The Torx drive provides positive engagement between the screw and installation tool, allowing stable torque transmission during manual, powered, and repeated assembly. ISO 14584 screws can be manufactured in stainless steel, carbon steel, and alloy steel with different strength grades and surface finishes, making them suitable for equipment components, sheet metal assemblies, electrical devices, machinery, and other applications where the head profile and drive configuration need to match the product design.
Specification:
ISO 14584 Torx Raised Countersunk Head Screws are specified by their raised countersunk head dimensions, hexalobular recess size, and metric thread parameters. Important specifications include thread diameter, pitch, screw length, head diameter, head height, countersunk dimensions, and Torx drive size, which determine the correct fit and installation performance of the screw.
These screws are available in a range of materials and mechanical grades to suit different operating conditions. Stainless steel versions such as A2-70 and A4-70 are commonly supplied for applications requiring corrosion resistance, while carbon steel grades such as 8.8 are suitable for general industrial fastening. Alloy steel versions with higher strength grades, including 10.9 and 12.9, can be provided for applications requiring greater tensile strength and load capacity. Surface finishes such as plain stainless steel, zinc plating, black oxide, and customized coatings are available according to customer requirements.

Dimension Chart of ISO14584 Torx Raised Countersunk Head Screws:
The dimension chart of ISO 14584 Torx Raised Countersunk Head Screws provides detailed measurements of the screw head profile, hexalobular recess, and thread dimensions defined by the standard. Key dimensions include thread diameter, screw length, head diameter, raised head height, countersunk head angle, and Torx recess size.
The raised countersunk head geometry determines how the screw seats against the mating surface and provides a controlled head projection after installation. Accurate control of head dimensions and drive recess specifications ensures proper tool engagement, consistent assembly performance, and compatibility with standard components. Customized dimensions and special requirements can also be supplied according to customer drawings.

Application of ISO14584 Torx Raised Countersunk Head Screws:
ISO 14584 Torx Raised Countersunk Head Screws are designed for assemblies where a smooth head transition, accessible fastening point, and reliable installation are required. The raised countersunk head provides a visible but low-profile fastening solution, making these screws suitable for machine covers, equipment panels, housings, fixtures, and components where the screw head needs to integrate with the product design while maintaining convenient access for assembly and maintenance.
Depending on the operating environment and mechanical requirements, ISO 14584 screws are available in different materials and strength grades. Stainless steel A2-70 and A4-70 versions are commonly used in food processing equipment, laboratory devices, electrical enclosures, and corrosion-sensitive machinery, while carbon steel and alloy steel grades such as 8.8, 10.9, and 12.9 are suitable for industrial equipment, automation systems, molds, and mechanical components requiring higher strength and durability. The hexalobular drive also makes them suitable for production environments using electric or automated fastening tools.
