Superior Material and Manufacturing Standards
These ANSI 18.2.2 Black Nuts are forged from ASTM A194 Grade 2H material. A194 2H is a high-strength grade of medium-carbon alloy steel, quenched and tempered to deliver exceptional tensile strength and hardness, effectively resisting deformation and galling under high-pressure conditions. The thread is typically coarse, which not only facilitates rapid assembly but also provides excellent fatigue resistance and stripping resistance, making it especially suitable for cast iron or soft alloy substrates.

Surface and Performance Characteristics
The product features a distinctive black oxide finish. This dense black oxide layer not only gives the ANSI 18.2.2 Black Nut a uniform matte black appearance but also provides basic rust resistance and mild corrosion protection. It effectively reduces the friction coefficient during thread engagement and prevents cold welding. Manufactured to Class A accuracy, these nuts achieve near-perfect thread engagement with bolts, ensuring uniform load distribution across all threads and preventing loosening even under severe vibration.
