Product Details
Our DIN 7984 screws are defined by their specialized low-profile design, high-strength material, and protective coating.
- DIN 7984 Low-Profile Head: The defining characteristic of this screw is its “low head” or “thin head,” which is engineered to be substantially shorter than a standard DIN 912 socket cap screw. This allows for installation in shallow counterbores or in applications where a protruding head would cause interference, enabling sleek, compact, and near-flush designs.
- High-Strength Carbon Steel: These screws are manufactured from quality carbon and alloy steel to achieve a range of property classes, including 4.8, 8.8, 10.9, and 12.9. This ensures they can deliver reliable clamping force and withstand significant tensile loads, making them suitable for both general-purpose and heavy-duty applications.
- Internal Hex Socket (Allen) Drive: The head features an internal hexagonal recess, designed for use with a hex key (Allen wrench). This drive style allows for high-torque tightening and is well-protected within the head, preventing external damage and ensuring a secure engagement.
- White Zinc Plated Finish: The screws are electro-galvanized with a layer of zinc. This coating acts as a sacrificial barrier, protecting the underlying steel from corrosion. The resulting bright, clear (or “white”) zinc finish is both functional and aesthetically clean, providing reliable rust resistance for indoor and general-purpose applications.

- Secure Internal Hex Drive: Enables high-torque installation with a standard hex key and protects the drive from external damage.
- Clean and Professional Appearance: The bright zinc finish offers a clean, professional look suitable for visible applications.
- DIN 7984 Standard Compliance: Manufactured to precise international standards, ensuring dimensional accuracy, consistent quality, and interchangeability.
Product Applications
The combination of a low-profile head and corrosion-resistant finish makes these screws ideal for a wide range of industries:
- Electronics: Perfect for mounting circuit boards, securing enclosures, and fastening components within compact electronic devices where space is limited.
- Precision Machinery: Used in tooling, jigs, and fixtures where a near-flush surface is required to avoid interference with moving parts.
- Automotive Industry: Employed for fastening interior trim panels, dashboard components, and other assemblies where a low-profile head is necessary.
- General and Heavy Industry: Suitable for machine guards, access panels, and other general fastening tasks where a compact head and moderate corrosion resistance are beneficial.
- Medical Devices: The low-profile design is advantageous for assembling compact and sleek enclosures for various types of medical equipment.
