Product details
PTFE and zinc aluminium flake coated fasteners are specialized fasteners designed to deliver superior corrosion resistance, reduced friction, and enhanced durability. These fasteners are coated with a unique combination of PTFE (Polytetrafluoroethylene) and zinc aluminium flake, which provides an excellent protective barrier against harsh environmental conditions including moisture, chemicals, and extreme temperatures. The PTFE coating offers low friction and anti-seize properties, facilitating easy installation and removal without galling or wear. Zinc aluminium flake provides robust anticorrosive protection to the base metal by forming a stable, sacrificial layer that prevents rust and oxidation. Ideal for use in automotive, aerospace, construction, and industrial machinery applications, these coated fasteners extend the service life of joints exposed to demanding environments, reduce maintenance frequency, and improve operational efficiency. They are compatible with a wide variety of substrates and available in various sizes and forms tailored to customized engineering requirements.

Frequently asked by buyers
How does the PTFE and zinc aluminium flake coating improve the fastener's performance?

The PTFE layer reduces friction and prevents galling during tightening and loosening, while the zinc aluminium flake layer provides robust corrosion resistance by acting as a sacrificial barrier to oxidation and rust.

Can these coated fasteners withstand exposure to salt spray and harsh chemicals?

Yes, these fasteners are tested to meet or exceed ISO 9227 Salt Spray standards with over 1200 hours of corrosion resistance, making them suitable for harsh chemical and marine environments.

Are these coatings compatible with all types of steel fasteners?

They are compatible with common steel and alloy steel fasteners typically used in automotive and industrial sectors, without compromising mechanical strength.

What is the operating temperature range for these coated fasteners?

They can operate effectively within a temperature range from -50°C to +250°C, suitable for most industrial and automotive applications.

Does the coating affect the mechanical strength of the fasteners?

No, the coating process is designed to maintain the mechanical integrity and strength of the base fastener material.
