PTFE Coated Stainless Steel Slotted Cheese Head Screws, available in sizes ranging from M5 to M8 with lengths between 8mm and 100mm. These high-quality screws feature a cylindrical head with a flat top and a single slot, allowing for easy tightening and loosening with a flat-blade screwdriver. Crafted from premium stainless steel and coated with PTFE (Polytetrafluoroethylene), they offer exceptional corrosion resistance, low friction, and enhanced durability. The PTFE coating provides a non-stick surface and excellent chemical resistance, making these screws ideal for applications in harsh environments, woodworking, furniture assembly, and general construction, where reliable and long-lasting fastening solutions are essential.
Metric Size – M5, M6, M8
Length (mm) – 8, 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 100
PTFE (Polytetrafluoroethylene) coated stainless steel combines the benefits of both materials to form a versatile and highly functional composite. Here's an overview of its properties:
- Corrosion Resistance: Stainless steel's natural corrosion resistance, thanks to its chromium content, is further enhanced by PTFE, providing excellent protection against rust, chemicals, and environmental degradation.
- Low Friction: PTFE's low coefficient of friction ensures smooth movement. When coated on stainless steel, it reduces surface friction, preventing wear and increasing durability.
- Chemical Inertness: PTFE is chemically inert and resistant to a wide range of chemicals. Applied to stainless steel, it enhances resistance to acids, bases, solvents, and corrosive substances.
- Temperature Stability: PTFE maintains its properties over a broad temperature range (-200°C to +260°C). Combined with stainless steel, it improves the material's ability to withstand extreme temperatures without losing integrity.
- Non-Stick Properties: PTFE's non-stick properties prevent substances from adhering to its surface, making it easy to clean and maintain when applied to stainless steel.
- Electrical Insulation: PTFE is an effective electrical insulator, preventing electrical conductivity. Coated on 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. Coated on stainless steel, it improves biocompatibility, reducing the risk of adverse reactions in biological systems.
What is a Slotted Cheese Head Screw?
A slotted cheese head screw is a fastener with a cylindrical head, a flat top, and a single slot across its diameter, allowing for tightening or loosening with a flat-blade screwdriver. These screws are commonly used in applications requiring frequent adjustments or removals, such as woodworking, furniture assembly, and general construction, offering secure and reliable fastening with easy accessibility and adjustment using common hand tools.
