PTFE-coated bolts and nuts are highly valued for their superior corrosion resistance, low friction, reliable tensioning, and ease of installation and removal. Comprehensive testing and field applications have demonstrated that fluoropolymer coatings are the future for Teflon-coated B7 stud bolts. Previously, hot-dip galvanized, cadmium, or zinc plating were standard for studs, but these coatings do not perform well in the corrosive environments common in many industries. PTFE-coated B7 studs, paired with 2H nuts, are now widely used across diverse applications due to their durability in challenging conditions.
As a leading manufacturer of PTFE-coated fasteners in India, we specialize in producing high-performance fasteners with exceptional corrosion resistance, durability, and low friction properties. Our PTFE-coated bolts, nuts, and studs are crafted to withstand challenging environments, including chemical processing, marine, and offshore applications.
