Standard: DIN7505
DIN7505 chipboard screws are professional-grade fasteners tailored for wood-based panel applications, adhering strictly to the German DIN 7505 standard—ensuring consistent quality, dimensional accuracy, and reliable performance trusted by global users.
Material: Crafted from high-tensile carbon steel (e.g., C1022, C1018) for exceptional strength, resisting deformation and breakage under load.
Surface Treatments: Available in electro-galvanized (Zn), hot-dip galvanized (HDG), and phosphate (Phos) coatings. Electro-galvanized for indoor dry environments; HDG for enhanced corrosion resistance in mild outdoor/humid conditions; Phos for improved paint adhesion, ideal for pre-finished projects.
Design Features: Full coarse thread for maximum grip in chipboard, MDF, plywood, and particleboard; sharp self-tapping point eliminates pre-drilling (for most panels), reducing installation time and board splitting risk; compatible with Phillips (PH), Torx (TX), or Hex (Allen) drives for versatile tool use.
