PTFE Coated Stainless Steel Hex Socket-Cylinder Head Cap Screws (DIN 912) conform to the following Standards/Norms:
DIN: 912
PTFE Coated Stainless Steel Hex Socket-Cylinder Head Cap Screws, available in sizes ranging from M5 to M12 with lengths between 8mm and 120mm. These high-performance screws are crafted from premium stainless steel and feature a PTFE (Polytetrafluoroethylene) coating that offers outstanding corrosion resistance, reduced friction, and enhanced wear protection. The PTFE coating provides a sleek, non-stick finish, making these screws ideal for applications in chemical processing, marine environments, and other demanding conditions where durability and reliability are paramount. Perfect for industrial and specialised applications, these screws deliver superior performance and longevity.
Metric Size – M5, M6, M8, M10, M12
Length (mm) – 8, 10, 12, 14, 16, 18, 20, 22, 25, 30, 35, 40, 40, 50, 60, 70, 80, 90, 100, 110, 120
PTFE (Polytetrafluoroethylene) coated stainless steel combines the desirable properties of both materials to create a versatile and highly functional composite. Here's a brief overview of its properties:
Corrosion Resistance: Stainless steel inherently resists corrosion due to its chromium content, while PTFE adds an additional layer of protection, making the material highly resistant to rust, chemicals, and environmental degradation.
Low Friction: PTFE is known for its low coefficient of friction, providing smooth and easy movement. When coated onto stainless steel, it reduces friction between surfaces, preventing wear and enhancing durability.
Chemical Inertness: PTFE is chemically inert and resistant to a wide range of chemicals. When applied to stainless steel, it enhances the material's resistance to acids, bases, solvents, and corrosive substances.
Temperature Stability: PTFE exhibits exceptional thermal stability, maintaining its properties over a wide range of temperatures (-200°C to +260°C). When combined with stainless steel, it enhances the material's ability to withstand extreme temperatures without losing its integrity.
Non-Stick Properties: PTFE has excellent non-stick properties, preventing adhesion of substances to its surface. When coated onto stainless steel, it creates a non-stick surface that is easy to clean and maintain.
Electrical Insulation: PTFE is a good electrical insulator, providing resistance to electricity and preventing electrical conductivity. When applied to stainless steel, it enhances the material's electrical insulation properties.
Biocompatibility: PTFE is biocompatible and inert to biological tissues, making it suitable for medical and pharmaceutical applications. When coated onto stainless steel, it enhances the material's biocompatibility, reducing the risk of adverse reactions in biological systems.
What are Hex Socket-Cylinder Head Cap Screws?
Hex socket-cylinder head cap screws are fasteners with a cylindrical head and a hexagonal recess for tightening or loosening using an Allen wrench or hex key. They offer high strength and precision, commonly used in machinery, automotive, and engineering applications, where reliable, flush fitting and torque control are required.
