USA Stainless 18 8 Hex Nut ASTM F594 (Inch)

Our Stainless Steel 18‑8 Hex Nuts (ASTM F594) are engineered for excellent corrosion resistance, dependable fastening strength, and long‑term durability across industrial, marine, construction, and general‑purpose applications. Manufactured from 18‑8 stainless steel—an alloy equivalent to 304 stainless—these nuts provide superior resistance to rust, moisture, chemicals, and outdoor exposure.

Built to meet ASTM F594 specifications, these hex nuts offer consistent mechanical properties, accurate thread engagement, and reliable clamping force when paired with stainless steel bolts, screws, and threaded rod. Their standard hex profile ensures easy installation with common hand tools, making them suitable for structural frames, machinery, fabrications, electrical enclosures, HVAC systems, and equipment assembly where corrosion protection is essential.
