Hexagon socket black zinc plated

El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.

Hexagon socket black zinc plated(also known as a black galvanized hex socket screw o black zinc Allen bolt) is a type of fastener with a hexagonal recess (internal drive) and a black galvanized coating for corrosion resistance and aesthetics. Below is a detailed description:

1. Material & Construction

• Base Metal: Typically made from carbon steel, alloy steel, or stainless steel for strength.

• Black Galvanized Coating: Achieved through zinc plating with a black chromate or black oxide finish, providing corrosion resistance and a dark, matte-black appearance.

2. Common Applications

• Machinery & Automotive: Used in engines, transmissions, and structural assemblies where a clean, corrosion-resistant fastener is needed.

• Electronics & Appliances: Provides a secure, low-profile fastening solution.

• Furniture & Construction: Offers a discreet yet durable fastening method.

• Hexagon socket black zinc plated

3. Advantages Over Standard Screws

• Higher Torque Capacity: The internal hex design allows for greater tightening force without stripping.

• Space-Saving: No protruding head, making it ideal for tight spaces.

• Enhanced Durability: Black galvanized coating resists moisture, chemicals, and wear better than plain steel.

4. Maintenance & Considerations

• Avoid Over-Tightening: The hex socket can strip if excessive force is applied.

• Limited Reusability: The black coating may wear off if frequently removed/reinstalled.

• Compatibility: Ensure correct thread size, pitch, and socket size (e.g., 4mm Allen key for M6 screw).

Conclusion

Black galvanized inner hexagon screws are a durable, corrosion-resistant, and visually appealing fastening solution, widely used in industries where both function and aesthetics matter. They are particularly favored in automotive, machinery, and high-end consumer products due to their strength and sleek appearance.
