Designed to maximize grip in relatively soft materials like particleboard.

features a flat, milled area under the head (φρεζάτη) that enables flush seating and reduces surface splitting. The thread geometry provides enhanced withdrawal resistance without pre-tapping in most cases. Form B offers a pan head profile for clean surface mounting.

Cross-references other standards, such as DIN EN ISO 4757 for cross-recess drives or ISO 898 for mechanical properties.

The sharp point allows for easy driving without pre-drilling in most softwoods and medium-density composites.

A crucial point for any professional is that the with a draft dating back to 1986 . It is now officially labeled as "Withdrawn" (ZURÜCKGEZOGEN). This does not mean the screws are obsolete. It means that for new product development, global manufacturers are expected to transition to its newer international successors, primarily ISO 1479 for cross-recessed head tapping screws.

Common surface finishes include zinc plating (white, blue, yellow, or black), hot-dip galvanizing, black oxide, phosphating, nickel plating, and Dacromet coating.

The specifies requirements for chipboard screws (also known as particle board screws), which are widely used in furniture manufacturing and woodworking. These screws are specifically engineered to provide high grip strength in low-density materials like chipboard, MDF, and softwoods without causing the material to split. Core Technical Specifications

Often features a partial thread or a "grooved shank" design to allow easier penetration without splitting the wood.

Designed to sit flush with or just below the wood surface. It is the industry standard for general cabinetry, furniture assembly, and hinge installation where a smooth surface is mandatory. DIN 7505 Type B (Pan Head / Raised Countersunk Head)

While the full technical tables are found in the official PDF, the standard generally categorizes screws into two primary types based on head design:
