fevicon-logoWhat are ASTM A194 Gr 2H Xylan Coated Hex Nuts?

ASTM A194 Grade 2H Hex Nuts are strong carbon steel fasteners made for use in high pressure and high temperature situations. The Xylan coating is a fluoropolymer based finish that makes surfaces easier to lubricate, more resistant to corrosion and chemicals, and less likely to wear down. These nuts meet the standards set by ASTM A194 and ASME B18.2.2, which means it is strong and the dimensions are accurate.


Stainless steel gr 2h hex nut and ss grade 2h hex nuts offer strong mechanical performance with strong heat and tensile resistance. SS gr 2h xylan nuts come in a full range of sizes and have standard or custom thread finishes. It is useful in many industries, including oil and gas, power, marine and processing.


fevicon-logoBenefits of A194 Gr 2H Xylan Coated Nuts

Our A194 Grade 2H Xylan-Coated Nuts combine strength and advanced protection, making it ideal for demanding environments.

  • Corrosion Resistance: The Xylan coating gives these nuts strong protection against rust, moisture, and harsh chemicals, ensuring long service life in wet or exposed environments.
  • Low Friction: The slick finish allows the nuts to be installed and removed easily, even in tight or hard-to-reach spaces.
  • Wear & Galling Resistance: The coating helps prevent scuffing, sticking, and seizure during repeated tightening or loosening on threaded studs or bolts.
  • High Strength: Made from Grade 2H material, these nuts offer exceptional strength and withstand high stress and heavy loads reliably.
  • Temperature Stability: They maintain shape and performance even under high temperatures such as in boilers, heaters, or exhaust systems.
  • Chemical Resistance: Xylan provides strong resistance against acids, alkalis, and aggressive industrial chemicals, making them ideal for refineries and chemical plants.
  • Dimensional Accuracy: Each nut is precisely machined for consistent threading and a secure, wobble-free fit.
  • Long Service Life: The durable steel combined with the tough Xylan coating reduces wear and maintenance needs, supporting uninterrupted operations.

These features make a194 gr 2h nuts and SS xylan 2h nuts a smart pick for the most challenging jobs in energy, marine, and chemical sectors.
