USA 2H Heavy Hex Nut, A194 / Sa 194, Hot-Dip Galvanization Blue Dye & Wax (Inch)
USA-made 2H Heavy Hex Nuts A194 / SA 194 Hot-Dip Galvanized with Blue Dye & Wax are premium high-strength fasteners designed for superior corrosion protection and smooth assembly performance. Manufactured in compliance with ASTM A194 / ASME SA 194 Grade 2H specifications, these nuts feature a heavy hex design that provides increased bearing surface and torque strength. The hot-dip galvanization delivers a thick, durable zinc coating, while the added blue dye and wax layer enhance visual identification, lubricity, and installation consistency.
Proudly manufactured in the USA, these A194 / SA 194 Grade 2H Heavy Hex Nuts are engineered for use with A193 Grade B7 bolts and other high-strength fasteners in demanding environments. The blue dye and wax treatment reduce friction during tightening, ensuring accurate preload and preventing galling. Ideal for use in structural steel, oil and gas, and marine applications, the combination of hot-dip galvanization and wax finish provides exceptional corrosion resistance and long-term performance even in harsh outdoor or coastal conditions.
