تفاصيل المنتج

Our ISO 7380 Button Head Screws are engineered for consistency and reliability in high-volume applications. The base material is a robust carbon steel, which is heat-treated to achieve a variety of property classes (from 4.8 to 12.9) to meet diverse strength requirements. The key feature is the protective White/Blue Zinc Plating. This is an electro-galvanization process where a layer of zinc is applied to the steel. The screw is then passivated with a chromate conversion coating.

• White Zinc (Clear/Silver) provides a bright, clean finish and good corrosion resistance for indoor or mild environments.
• Blue Zinc (Iridescent Blue/Clear) is a slightly thicker trivalent chromate passivation that offers enhanced corrosion resistance and better performance in salt spray tests compared to standard white zinc.

The screw’s design adheres to the ISO 7380 standard, featuring a smooth, dome-shaped “button” head that provides a wide bearing surface and a snag-free finish. This is paired with a clean, deep internal hex socket (Allen drive) for secure, high-torque installation.

ميزات المنتج

Our zinc-plated ISO 7380 screws are designed with features that deliver significant benefits for wholesale and manufacturing clients.

• Economical and Effective Corrosion Protection: Zinc plating is one of the most cost-effective methods for protecting carbon steel from rust, making these screws an ideal choice for large-scale production where budget is a key consideration.
• Enhanced Durability with Blue Zinc Option: The blue zinc finish provides a superior level of corrosion resistance, extending the service life of assemblies in environments with moderate humidity or temperature fluctuations.
• Aesthetic and Functional Head Design: The low-profile, dome-shaped head offers a clean, modern, and finished look. Its wide bearing surface is ideal for fastening thinner materials without causing damage, and its smooth contour is safe and snag-free.
• Versatile Strength for Diverse Applications: With availability in property classes from standard 4.8 to high-tensile 12.9, these screws can be used for everything from decorative paneling to light-duty structural connections.
• Optimized for Efficient Assembly: The crisp internal hex socket provides a secure grip for Allen keys and automated drivers, allowing for fast, reliable, and slip-free installation on a busy production line.

The practical design and cost-effective nature of these screws make them a staple in numerous industries. They are extensively used in the furniture industry for the assembly of flat-pack (RTA) furniture, cabinetry, and office desks. In electronics manufacturing, they are perfect for securing chassis, enclosures, server racks, and internal mounting brackets. The automotive sector uses them for attaching interior trim, dashboard components, and various non-structural brackets. They are also a go-to fastener in general manufacturing for attaching machine guards, access panels, and control boxes. Additionally, their clean appearance makes them suitable for retail fixtures, shelving units, and point-of-sale displays.
