Quantity
The Fujian A194 2H Nut is a high-strength heavy hex nut manufactured in compliance with ASME B18.2.2 standards, crafted from ASTM A194 Grade 2H material. Available in sizes ranging from 5/16 to 4 inches with 4-1/2 UNC thread specifications, this nut delivers exceptional performance in demanding industrial environments. The PTFE (polytetrafluoroethylene) coating provides superior corrosion resistance and low-friction properties, making it ideal for high-strength and highly corrosive applications.
PTFE Coating Characteristics
The PTFE coating, typically 15-25 microns thick, offers outstanding corrosion resistance across a pH range of 0-14, effectively resisting strong acids (sulfuric, hydrochloric, nitric), strong alkalis (sodium hydroxide, potassium hydroxide), and various organic solvents. The coating maintains stability from -200°C to +260°C and features an extremely low dynamic friction coefficient of approximately 0.05-0.1, reducing wear on mechanical components and extending service life.
