The defines the specifications for chipboard screws (also known as particle board screws), specifically those featuring a cross-recess or star-recess head. These screws are designed for fastening chipboards, particle boards, wood, and similar materials, commonly used in furniture manufacturing, interior applications, and construction.
The standard describes screws with a cross recess (typically Type Z/Pozidriv) and a countersunk head. Global Fastener Platform
Provides basic corrosion resistance and a bright metallic finish. din 7505 standard pdf
The standard defines two main forms—Form A (countersunk head) and Form B (raised countersunk head). Form A is the most commonly utilized variant. Dimensions and Tolerances (DIN 7505-A)
For R&D or private study, some national standards bodies allow viewing in read-only mode, but for manufacturing or quality control, purchase the official version. The defines the specifications for chipboard screws (also
| Feature | Specification | Key Advantages | | :--- | :--- | :--- | | | Self-tapping with a sharp 40-degree thread angle , coarse pitch, deep threads. | Cuts into material, reduces splitting, increases pull-out resistance and holding strength in softwoods and engineered wood. | | Point Geometry | Sharp, self-starting point. | Enables easy installation without pre-drilling in many materials, saving time. | | Drive Types | Primarily Pozidriv (PZ) , available with Torx (6-lobe) or Phillips drives. | Better torque transmission, reduces "cam-out" (slippage) and tool wear for efficient installation. | | Head Styles | Countersunk (Form A) : sits flush with the surface for a smooth finish. Pan Head (Form B) : has a slightly raised, rounded top. Raised Countersunk : a hybrid between the two. | The Form A (Countersunk) is the most common for furniture, while Form B (Pan Head) is often used where the head will remain visible or needs to clamp a larger area. | | Manufacturing Process | Cold forging : Shaped at room temperature from wire. | Creates a strong, durable, and precisely shaped fastener. |
The DIN 7505 standard is essential for specifying and using chipboard screws. Although it's a draft, it remains a vital benchmark, defining a screw's unique geometry, materials, and performance. Understanding its technicalities empowers you to select the right fastener for your application. Dimensions and Tolerances (DIN 7505-A) For R&D or
Screws manufactured under this standard are typically made from case-hardened carbon steel or stainless steel (A2 or A4 grades for corrosion resistance). Carbon steel versions are usually coated with: Yellow zinc plating (Zinc Dichromate) Clear/White zinc plating Black oxide Why You Need the DIN 7505 Standard PDF
Acquiring the official DIN 7505 standard PDF is a strict requirement for quality assurance departments. The document provides the exact metrics for:
The real magic of a DIN 7505 screw lies in its "self-tapping" nature. According to experts at ITA Fasteners , these screws feature coarse threads that allow them to sit perfectly on the chipboard surface without the need for a pre-drilled pilot hole.

DIN 7505 is a German standard developed by the Deutsches Institut für Normung (DIN) organization, which is responsible for establishing and maintaining standards in Germany. The standard specifically focuses on self-tapping screws, also known as tapping screws or thread-cutting screws. These screws are designed to create their own threads in a material, usually metal or plastic, without the need for a pre-drilled hole or a separate tapping operation.
