Usually made from carbon steel (often zinc-plated) or stainless steel for corrosion resistance. 2. DIN 7505 Technical Specifications (Form A)
: Includes minimum torsional resistance values (e.g., 3.0 N.m for a 4mm screw) and a surface hardness of at least 450 HV. Global Fastener Platform Critical Technical Data Table din 7505 standard pdf
: Unlike generic wood screws, DIN 7505 screws have a thinner core and higher threads, which provide better grip and prevent the wood from splitting—specifications backed by this document. Usually made from carbon steel (often zinc-plated) or
If you are working in a European or global environment that uses metric ISO threads, remains the gold standard. Global Fastener Platform Critical Technical Data Table :
The DIN 7505 standard defines a screw type designed for engineered wood materials like chipboard, MDF, and plywood. Their design directly addresses the challenges of working with these materials, preventing splitting while ensuring a strong, secure hold.
While official DIN standards must typically be purchased, technical data sheets and detailed summaries are available from manufacturers and document repositories: Technical Summary
