Hexagonal Head Black Zinc Plating – Comprehensive Description

Hexagon head black zinc plated refers to a type of metal fastener (such as bolts, screws, or nuts) featuring a six-sided (hexagonal) head and a black zinc-coated finish. This combination provides both functional mechanical strength and enhanced corrosion resistance with an aesthetically dark appearance.

1. Hexagonal Head Design

• Shape: Six flat sides (hexagon) for tool engagement.

• Tool Compatibility: Driven by wrenches (spanner, socket, or Allen keys, depending on the subtype).

• 一般的なタイプ：

  • Hex Head Bolts/Screws – Standard external wrenching.

  • Hex Flange Head – Integrated washer-like flange for load distribution.

  • Hex Socket Head (Allen Bolt) – Internal drive with a hexagonal recess.

2. Black Zinc Plating Finish

• ベース素材： Typically carbon steel or alloy steel.

• 登場： Matte black or dark gray with slight iridescence.

• Hexagon head black zinc plated

• Thickness: Typically 5–15 microns (including zinc layer + black topcoat).

3. Key Properties & Benefits

• 耐食性： Better than bare steel but less than hot-dip galvanizing; suitable for indoor or mildly corrosive environments.

• 美的アピール： Dark finish reduces glare and blends well in machinery, automotive, and electronics.

4.共通アプリケーション

• 自動車： Engine components, brackets, and interior fittings.

• Machinery & Equipment: Assembly parts requiring corrosion resistance.

• Electronics & Enclosures: Black screws for aesthetic and anti-reflective purposes.

• Furniture & Construction: Decorative fasteners with moderate rust protection.

• Hexagon head black zinc plated

結論

Hexagonal head black zinc-plated fasteners offer a balance of functionality, corrosion protection, and visual appeal, making them a popular choice for industrial, automotive, and decorative applications where moderate environmental resistance is sufficient.
