ISO14583 Hexalobular Socket Pan Head Screws
ISO 14583 Hexalobular Socket Pan Head Screws are precision-engineered fasteners designed with a pan head and hexalobular internal drive according to ISO 14583 standards. The hexalobular socket (Torx) design provides better contact between the screw and driver, allowing higher torque transmission with reduced risk of cam-out and drive damage during installation. Compared with conventional cross recess or slotted screws, these screws offer more reliable tightening performance, improved assembly efficiency and longer service life. The pan head design provides a larger bearing surface while maintaining a relatively low head profile, making them suitable for applications where secure fastening and limited installation space are required.
Manufactured from high-quality stainless steel, alloy steel or other engineering materials, ISO 14583 Hexalobular Socket Pan Head Screws provide excellent mechanical performance, dimensional accuracy and consistent quality. Their compact head design, strong drive engagement and clean appearance make them widely used in precision equipment, electrical products, machinery, automotive components and industrial assemblies. Available in various diameters, lengths, strength classes and surface finishes, these hexalobular socket pan head screws can meet different fastening requirements and provide reliable solutions for both standard and customized applications.

Mechanical Property:
Carbon and Alloy Steel ISO14583 Screws — ISO 898-1
ISO 14583 hexalobular socket pan head screws made from carbon and alloy steel are supplied in different property classes according to ISO 898-1. Common property classes include 4.8 and 8.8, depending on screw dimensions and material requirements. The standard specifies mechanical properties such as tensile strength, yield strength, proof load and hardness to ensure the required strength and fastening performance.
Stainless Steel ISO14583 Screws — ISO 3506-1
Stainless steel ISO 14583 screws are classified according to ISO 3506-1, which specifies mechanical properties for corrosion-resistant stainless steel fasteners. Common material designations include A2-70 and A4-70, depending on the selected stainless steel grade and product requirements. Mechanical properties include tensile strength and 0.2% proof stress, while the material grade determines the screw’s corrosion resistance in different service environments.
