Hexagon head black zinc plated

Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.

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

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

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

• Common Types:

  • 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

• Base Material: Typically carbon steel or alloy steel.

• Appearance: 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

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

• Aesthetic Appeal: Dark finish reduces glare and blends well in machinery, automotive, and electronics.

4. Common Applications

• Automotive: 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

Conclusion

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.
