Load Capacity: Varies by size (e.g., 1/2" washer ~2,500 lbs tensile strength)

Corrosion Resistance: Excellent in saltwater and marine environments

Coating: Optional zinc or Xylan coating for added protection

Thread Type: Compatible with UNC, UNF, or metric threads

Packaging: Bulk, bags, or custom packaging

Marine Grade Stainless Steel Washers and Marine Hardware typically comply with maritime standards such as ASTM F593 (for stainless steel bolts, nuts, and washers) and ASTM A276 (for stainless steel bars and shapes). These standards ensure corrosion resistance and durability in marine environments. Always verify specific product certifications with the manufacturer.
