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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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 Slotted Hexagon Head Bolts?

Slotted hexagon head bolts are fasteners with a hexagonal head and a single slot (or "cheese") across the head's diameter. This slot allows for tightening or loosening using a flat-blade screwdriver or a slotted screwdriver. These bolts are commonly used in applications where frequent adjustments or removals are required, such as in machinery, automotive assembly, and construction. The hexagonal head provides a secure grip for tightening with a wrench or spanner, while the slot allows for easy accessibility and adjustment with common hand tools.
