standard defines the technical specifications and dimensions for chipboard screws
(also known as particleboard screws). These fasteners are engineered specifically for joining wood-based materials like particleboard, MDF, and plywood. Alibaba.com Key Features of DIN 7505 Screws Thread Design din 7505 standard pdf
: Features a coarse, continuous thread with a pitch often twice that of standard wood screws, providing aggressive biting action and high pull-out resistance in low-density substrates. Self-Tapping/Cutting Tip
: Many variants include a sharp or self-drilling point that eliminates the need for pre-drilling in most softwoods. Head Style : Primarily available as a
(countersunk flat head) with a 90° angle, allowing it to sit flush with the material surface. Drive Type : Typically uses a Pozidriv (PZ)
or Phillips (PH) cross-recess. Pozidriv is preferred for power tools to reduce "cam-out" (slipping). ITA Fasteners Technical Specifications
Dimensions for DIN 7505 screws vary by manufacturer, but standard metric sizes typically range as follows: Common Range Nominal Diameter (d) 2.5 mm to 6.0 mm Head Diameter (dk) 5.0 mm to 12.0 mm Thread Pitch (P) 1.1 mm to 2.6 mm Socket Size No. 1 (for 2.5–3mm) to No. 3 (for 6mm) Length (L) 10 mm up to 150 mm Materials & Finishes
To suit different environments, these screws are manufactured in several variants: Zinc Plated (Yellow/White)
: Most common; offers moderate corrosion resistance for indoor furniture. Stainless Steel (A2/A4)
: High durability for moisture-prone areas like kitchens, bathrooms, or outdoor settings. Black/Grey Phosphate | Standard | Region | Material Removal |
: Often used for drywall-specific variants to provide mild rust resistance and better paint adhesion. DIN 7505 Chipboard Screw Specifications | PDF - Scribd
The DIN 7505 standard provides the essential technical specifications for chipboard screws, which are also commonly known as particle board screws. These fasteners are designed for high-performance use in engineered wood products such as MDF and chipboard, as well as natural soft and hard woods.
If you are looking for a DIN 7505 standard PDF, you will typically find it contains critical data on dimensions, thread pitch, and head forms to ensure structural integrity in woodworking and furniture assembly. Overview of DIN 7505 Technical Specifications
The DIN 7505 standard defines the geometry and material requirements for self-tapping screws that can be driven into wood surfaces without a pilot hole. Specification Details Material Carbon steel (typically C1022A) or Stainless Steel (A2/A4) Thread Type Coarse, deep threads for maximum grip and minimum strip-out Common Sizes Diameters from 2.5mm to 6mm; lengths from 13mm to 150mm Finish Options
Yellow Zinc, Blue Zinc (Galvanised), Phosphate, or Nickel Plated Drive Types
Pozidrive (Type Z) is standard, but Torx and Square drives are also used Common Forms of DIN 7505 Screws
The standard is often divided into "Forms" based on the head shape of the screw: ITA Fastenershttps://itafasteners.com Chipboard Screws | DIN 7505 Metric - ITA Fasteners
At the time of writing, the DIN 7505 standard PDF typically costs between €80 and €120 ($85–$130 USD), depending on the language version (German or English). A "read-only" version may be slightly cheaper, while a single-user PDF with print permissions costs more. Suggested concise citation formats
A: Generally, no. DIN 7505 is intended for softer materials (aluminum, zinc, plastics). Thread-forming in steel would require excessive torque and likely break the screw. For steel, refer to DIN 7500-2 (thread-rolling screws).

Key definitions found in the text usually include:
The "100 kg Problem": One specific nuance often referenced in older versions of DIN 7505 regarding masses was the "100 kg rule" for user payload. The text details how manufacturers must calculate the minimum payload allowance, ensuring the user has a realistic capacity for luggage.
