Professional Applications & Engineering Value

This C276 Nickel hex nut delivers critical performance where standard fasteners fail. The Hastelloy C-276 alloy provides unparalleled resistance to pitting, stress corrosion cracking, and oxidizing agents up to 1900°F. Engineered with 1/2"-13 UNC coarse threads and Class 2B thread fit, it maintains secure connections in high-vibration equipment while allowing rapid assembly. The external hex drive accommodates standard wrenching tools for simplified maintenance in confined spaces. Ideal for chemical processing systems, marine hardware, and pollution control equipment, this nut eliminates galvanic corrosion concerns when paired with compatible nickel-alloy bolts, extending service life in critical installations.

Specification Summary & Compliance
