PTFE-coated B8 stud bolts are premium-grade fasteners designed for high-performance applications in demanding environments. Made from stainless steel conforming to ASTM A193 B8 specifications, these bolts are coated with polytetrafluoroethylene (PTFE), which provides exceptional resistance to corrosion, chemicals, and extreme temperatures. The PTFE coating also reduces friction, prevents galling, and enhances installation and removal processes.
These stud bolts are highly reliable in environments prone to chemical exposure, such as chemical processing plants, refineries, and offshore facilities. They also perform exceptionally well in high-temperature settings, making them suitable for heat exchangers, pressure vessels, and piping systems.
FastenMetal produce First-class specialized industries fasteners like stud bolts and nuts which made from a193 b7/b7m, b8/b8m,L7 and so on.For non standard stainless steel and exotic material fasteners (including non standard materials and sizes), we can usually offer as a manufactured special.
