Product Overview
Product Application
DIN 7505A is a countersunk head Phillips/Pozi-drive wood screw, specifically optimized for particleboard and softwoods (often referred to as particleboard screws or Spanplattenschrauben).
It is primarily used for particleboard, MDF, plywood, solid wood, and furniture assembly. Its countersunk design allows the screw to sit flush with the surface of the material after installation, resulting in a more aesthetically pleasing finish.

Specification
Geometry and Design Features
-
Head Style: Countersunk head (flat top with a cone-shaped bearing surface), typically with a 90° countersink angle.
-
Drive Type: Type A specifies a cross recess drive. In modern manufacturing, this is almost universally a Pozidriv (PZ) recess, though older variations or specific callouts might occasionally feature a Phillips (PH) drive. Pozidriv is preferred for chipboard screws to reduce cam-out under high torque.
-
Thread Profile: Features a deep, spaced thread with a sharp thread angle (usually around 40° to 45°). This aggressive thread profile allows the screw to cut cleanly into engineered wood products like MDF and particleboard without splitting the material.
-
Tip: A sharp, pointed tip (Type A) designed for quick grabbing and easy starting without requiring a pilot hole in most softwoods or chipboard.
Product Advantages
Flush Countersunk Finish
The countersunk head sits perfectly flush with the surface, delivering a clean and professional appearance.
Fast & Efficient Installation
Optimized thread geometry enables smooth driving and quick assembly, improving installation efficiency.
Common Questions
What materials is DIN 7505A suitable for?
It is primarily used for wood-based materials such as particleboard, MDF, plywood, softwood, and hardwood.
Is pre-drilling required before installation?
Pre-drilling is generally not required for softwood; however, it is recommended for hardwood or when installing near the edge of the board to prevent the wood from splitting.
What is the difference between DIN 7505A and standard wood screws?
DIN 7505A features a deep-thread design specifically optimized for particleboard, providing stronger holding power and making it particularly suitable for furniture and panel-based wood joints.
Are stainless steel versions available?
Yes, A2 and A4 stainless steel versions are available, suitable for both indoor and outdoor environments.
