ISO14580 Hexalobular Socket Cheese Head Screws
ISO 14580 Hexalobular Socket Cheese Head Screws combine a compact cheese head design with a hexalobular (Torx) drive system, providing an efficient fastening solution for assemblies where installation space is limited. Compared with conventional socket head cap screws, the lower-profile cheese head reduces the required installation space while maintaining reliable clamping performance and a clean finished appearance.
The hexalobular drive offers improved engagement between the tool and screw recess, allowing stable torque transmission and reducing the risk of drive damage during assembly. Manufactured according to ISO 14580 requirements, these screws are available in various materials including stainless steel, carbon steel, and alloy steel, with different strength grades and surface finishes to meet diverse application requirements. The hexalobular drive provides stable tool engagement and efficient torque transmission, making these screws suitable for precision machinery, automation equipment, electronic devices, automotive components, and other compact assemblies requiring secure and space-saving fastening solutions.

Mechanical Property:
Carbon and Alloy Steel Screws — ISO 898-1
ISO 14580 hexalobular socket cheese head screws made from carbon and alloy steel can be supplied in specified property classes, such as 8.8 and 10.9, subject to size and product requirements. ISO 898-1 defines their mechanical properties, including tensile strength, yield strength, proof load and hardness. The applicable property class should be selected according to the required strength and fastening conditions.
Stainless Steel Screws — ISO 3506-1
For stainless steel ISO 14580 screws, mechanical properties are specified according to ISO 3506-1, which classifies corrosion-resistant stainless steel fasteners by steel grade and property class. Common designations include A2-70 and A4-70, where applicable to the screw size and product requirements. Relevant properties include tensile strength and 0.2% proof stress, while the stainless steel grade is selected according to the required corrosion resistance and service environment.
