Question 1

What are coated fasteners and where are they typically used?

Accepted Answer

Coated fasteners are bolts, nuts, and screws treated with protective coatings to enhance corrosion resistance, reduce friction, and improve longevity. Coatings like PTFE, Xylan®, zinc-nickel, and HDG are applied to withstand harsh industrial environments. These fasteners are widely used in offshore rigs, chemical plants, wind turbines, infrastructure, and automotive systems. Their coating ensures long service life, reduced maintenance, and dependable mechanical performance in corrosive or high-load conditions.

Question 2

What types of coatings do you offer on fasteners and what are their benefits?

Accepted Answer

We offer PTFE , zinc-nickel, hot-dip galvanizing, cadmium, black oxide, and zinc-flake coatings. PTFE coatings reduce friction and resist chemical attack, ideal for marine and oilfield use. HDG coatings provide thick, durable zinc protection for infrastructure. Zinc-nickel and cadmium coatings are used in aerospace and automotive for superior wear and corrosion resistance. Each coating is tested to meet ASTM or ISO standards for salt spray and thickness.

Question 3

Can coated fasteners be customized for large-scale industrial projects?

Accepted Answer

Yes. We offer complete customization for coated fasteners including base material selection, thread type (metric/UNC/UNF), coating thickness, and fastener geometry. All fasteners are tested for coating adhesion and corrosion resistance, and come with third-party certifications, salt spray test reports, and MTCs. Our coated fasteners are supplied to EPC contractors, OEMs, and fabricators globally, supporting critical projects in energy, marine, chemical, and civil sectors.
