    Zeron 100 FG-Spec Hex Nuts, UNS S32760 Super Duplex Heat-Selected for FG Bolt Companions (ASME B18.2.2)

    Zeron 100 super duplex hex nuts, finished hex nuts per ASME B18.2.2

    Zeron 100 FG-spec hex nuts are super duplex stainless steel finished hex nuts (UNS S32760) per ASME B18.2.2 standard hex pattern, supplied as companions to FG hex bolts. Nuts ship in SA condition by necessity (hot-forged then SA + tapped); the heat lot is cherry-picked from FG-grade heats to ensure mechanical-property match with the FG bolt. For ANSI flange + high-load joints specify FG heavy hex nuts instead.

    FG-spec hex nut = SA-condition nut from FG-grade heat lot · Standard hex pattern · NACE ≤ 28 HRC

    Standards: ASME B18.2.2 + ISO 4032 + ASTM A1082 + ASTM F606 + NACE MR0175.
