What are ISO 14579 A2-70 Stainless Steel Torx Socket Head Cap Screws?
ISO 14579 screws are metric socket head cap screws featuring a cylindrical head and a six-lobe Torx, or hexalobular, drive recess. The cylindrical head provides a compact, raised bearing surface, while the internal Torx drive accepts a matching driver for secure installation in tapped holes or compatible threaded assemblies. These screws are designed for applications requiring a strong, reliable metric fastening connection with the benefits of a precision six-lobe drive.
What material are ISO 14579 A2-70 Stainless Steel Screws made from?
These screws are manufactured from A2 stainless steel with an A2-70 property class. A2 stainless steel provides good general corrosion resistance for industrial, automotive, mechanical, and outdoor applications, while the 70 property class indicates a minimum tensile strength of 700 MPa. This combination offers a useful balance of mechanical strength and corrosion resistance for a wide range of metric fastening requirements.
Why choose ISO 14579 A2-70 Stainless Steel Torx Socket Head Cap Screws?
The six-lobe Torx drive provides positive engagement with a matching driver, helping reduce cam-out and improving torque transfer during installation. The cylindrical socket head provides a compact profile suitable for machinery and equipment assemblies where a conventional external hex head may be less convenient. A2-70 stainless steel combines mechanical strength with corrosion resistance, making these screws a practical choice for applications requiring durable metric fasteners without the need for a plated steel finish.
Where are ISO 14579 A2-70 Stainless Steel Torx Socket Head Cap Screws commonly used?
ISO 14579 A2-70 stainless steel Torx socket head cap screws are commonly used in automotive manufacturing, motorcycles, motorsport equipment, industrial machinery, machine tools, automation systems, robotics, electrical enclosures, instrumentation, electronics, pumps, motors, gearboxes, appliances, and general mechanical assemblies. They are frequently used for securing machine components, mounting brackets, equipment housings, access covers, panels, fixtures, guards, and precision components where a reliable metric threaded connection and controlled installation are important.
A2 stainless steel makes these screws suitable for outdoor equipment, agricultural machinery, architectural hardware, commercial equipment, manufacturing systems, and general maintenance and repair applications where resistance to moisture and ordinary atmospheric corrosion is required. The Torx drive is particularly useful in OEM production, equipment assembly, machine building, fabrication, and service applications where repeatable installation and secure driver engagement are beneficial.
