Marine Grade Stainless Steel Nuts are corrosion-resistant fasteners designed for harsh marine environments. These nuts are made from high-quality stainless steel, typically 316 grade, offering superior durability and strength. They ensure reliable performance in saltwater and high-moisture conditions.

Size: M3 to M100 (metric), #4 to 4" (imperial)

Grade: 316 (A4), 304 (A2), 316L, 317L, 2205 (Duplex)

Viscosity: N/A (not applicable for solid fasteners)

Buoyancy: Neutral (density ~7.9-8.0 g/cm³, sinks in water)

Material: Austenitic or Duplex Stainless Steel (Cr-Ni-Mo alloy)

Corrosion Resistance: High (resists saltwater, chlorides, and acids)

Finish: Passivated, Electropolished, or Plain

Strength: 70-100 ksi (varies by grade and temper)

Temperature Range: -50°C to 250°C (short-term up to 400°C for some grades)

Standards: ASTM A193, ASTM A320, ISO 3506, DIN 934

Thread Type: Metric Coarse/Fine, UNC, UNF, BSW

Coating/Lubrication: Optional PTFE or Xylan for reduced galling

Marine Grade Stainless Steel Nuts and Fastening Systems typically comply with maritime standards such as ASTM F593 for stainless steel bolts, hex cap screws, and studs, and ASTM F594 for stainless steel nuts. These standards ensure corrosion resistance and durability in marine environments.
