What is a PTFE Coated Bolt?
It is a fastener (typically ASTM A193 B7 stud bolt) coated with a non-stick fluoropolymer. This coating provides exceptional corrosion resistance and a low coefficient of friction.

Top 3 Benefits of High Fasteners’ PTFE Coating:

Extreme Corrosion Resistance:Our PTFE/Xylan coated bolts can withstand over 3,000 hours of Salt Spray Test without red rust. This makes them ideal for subsea and marine applications.Controlled Torque (Low Friction):The "non-stick" nature of Teflon ensures that the nut runs down smoothly even after years of exposure. It prevents galling and ensures accurate preload during assembly.Color Coding for Safety:We offer customized colors (Blue, Green, Red) to help engineers identify different material grades or maintenance schedules instantly on-site.

Why Buy from High Fasteners?Unlike trading companies, Handan Hangfan Metal Products Co., Ltd. (High Fasteners) is a source factory.

Quality: We use Optical Sorting Machines to ensure thread integrity before coating.Capacity: 500 Tons/Month of B7/2H stud bolts.Price: Factory-direct pricing saves you 15-20% compared to local distributors.
