Usually made from carbon steel (often zinc-plated) or stainless steel for corrosion resistance. 2. DIN 7505 Technical Specifications (Form A)
If you need the official document for compliance, engineering audits, or manufacturing quality control, you can obtain it from:
: It details specifications for both countersunk (Type A) and pan head (Type B) versions. din 7505 standard pdf
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.
Once you have secured your , translating the tables into a successful assembly requires three steps. Usually made from carbon steel (often zinc-plated) or
: Defined by the German Institute for Standardization, DIN 7505 ensures consistency in the geometric and mechanical properties of screws used primarily in furniture manufacturing and interior construction. Self-Tapping Design
Below is an overview of the typical dimensions found in the standard charts: Nominal Diameter ( Head Diameter ( Head Height ( Recess Size (Pozidriv) 3.5 mm 4.0 mm 4.5 mm 5.0 mm 6.0 mm Note: Lengths ( The defines the specifications for chipboard screws (also
The technical drawing and datasheet (often found in a ) provide the following critical information: 1. Dimensions and Thread Profile
Designed to maximize grip in relatively soft materials like particleboard.
The standard defines the recess type used to drive the screw. While older variations might include simple slotted drives, modern DIN 7505 screws universally utilize:
The is a German national standard, also known by its English title "Particle board screws with cross recess type Z," developed by the Deutsches Institut für Normung (DIN). It lays down the precise requirements for a specialized type of fastener designed for engineered wood products.
