Product Introduction

Black nickel screws are fasteners made of high-quality black nickel plating technology. They have excellent corrosion resistance, oxidation resistance and excellent mechanical properties. With their unique black appearance and excellent protective function, this type of screw not only has unique advantages in aesthetics, but is also widely used in high-end fields such as aerospace, automobiles, electronics, furniture, decoration, etc., providing safe and durable connections for various equipment and structures.

Types of Black Nickel Screws

To adapt to different application scenarios, we provide a variety of types of black nickel socket screws, mainly including:

✔Hexagon head screws

✔Hexagon socket screws

✔Countersunk head screws

✔Cross slot/slot screws

✔Customized screws: Customize non-standard sizes, special head shapes or special coating effects according to your needs.

Alloy Type and Material Grade

Main Features

Black nickel socket screws are precision screws that form a dense black nickel coating on the surface of nickel alloy through an electroplating process. The characteristics include:

1.Multi-layer electroplating process: bottom nickel (≥5μm) + black nickel layer (3–8μm), enhanced corrosion resistance (salt spray test ≥500 hours).

2.Matte black aesthetics: uniform black surface (color difference ΔE≤1.5), no fingerprint residue, suitable for high-end display equipment.

3.Environmentally friendly and non-toxic: Complies with RoHS/REACH regulations, with no hexavalent chromium or cadmium release risk.

4.Functional advantages: stable conductivity (resistivity ≤ 1.5 μΩ·cm), anti-electromagnetic interference (EMI).
