Applications and selection
Furniture, panels and wood-based assemblies with a suitable screw specification.
State the substrate, screw diameter, length, head and drive. Do not describe a chipboard screw as a metal self-drilling screw without a matching specification.
Dimensions & technical reference
DIN 7505 (A):1986
Type A countersunk head. Diameter is in millimetres, not an M-thread designation. Confirm recess type, thread length and substrate suitability.

Catalog inquiry range: 3.5 - 6.0. Availability, lengths, grades and finishes are confirmed by quotation. Sizes outside the cited reference table require the applicable standard dimensions or an approved drawing. Quote the exact standard and edition; DIN, ISO and U.S. references are not automatically interchangeable.
Materials, surface finishes and standards
Materials for this series: Carbon Steel, Stainless Steel. Surface finishes: Electroplated, Zinc Plated, Stainless. Compatibility between the grade, finish and operating environment needs to be confirmed.
For titanium, nickel alloy or other non-ferrous requirements, include the exact material grade and drawing. Required mechanical properties, inspection documents and traceability should be stated in the inquiry.
Chipboard screws have application-specific thread and point geometry. No direct interchangeability with DIN 7505 is asserted. Standards from different systems can vary in dimensions, threads, product scope and test requirements. Confirm the exact designation and edition in the quotation.
Ordering standard
DIN 7505 (A):1986
United States references for a separate inquiry: ASME B18.6.1 (related inch wood-screw reference). Confirm the exact form, thread system and drawing before quoting.
What to send for a quotation
- Chipboard screws or your part number, with the relevant standard and edition.
- Exact dimensions, thread details, quantity and any critical tolerances.
- Material grade, surface finish, inspection requirements and delivery destination.
- For customization, a drawing revision and a description of the mating assembly.
Common questions about chipboard screws
How are chipboard screws different from self-drilling screws?
Their thread and point geometry address different substrates and installation methods. Select the screw for the material stack rather than using the names interchangeably.
Can I request a size or material outside this listing?
Yes. Send the required dimensions and exact material grade for review. A quotation is needed to confirm feasibility, price and lead time.
