Zinc Nickel Alloy Plated Grade 8.8 Alloy Steel Socket Head Cap Screws Fasteners High Salt Spray Resistance for Marine Offshore

Product Description

Product Highlights

1. Superior Corrosion Resistance

Zinc-nickel alloy plating provides up to 500-1000 hours salt spray resistance per ASTM B117, far exceeding traditional zinc plating. Ideal for marine, offshore and coastal environments.

2. High Strength Alloy Steel

Made from quenched and tempered alloy steel, available in Grade 8.8, 10.9 and 12.9, ensuring excellent tensile strength and durability for heavy-duty applications.

3. Cost-Effective Alternative to Stainless Steel

Zinc-nickel plated alloy steel delivers comparable corrosion performance at a lower cost than 304/316 stainless steel, helping you reduce project costs without sacrificing quality.

4. Precise Thread and Smooth Finish

Manufactured to DIN 912 / ISO 4762 standards with precision rolled threads. The uniform zinc-nickel coating provides a clean, silver-grey appearance with consistent thickness.

5. Wide Temperature Range

Stable performance from -50°C to +200°C, suitable for both outdoor exposure and high-temperature industrial equipment.
