DIN 96:2016 Round Head Slotted Wood Screw adopts a slotted round head and wood screw thread to meet the needs of general fastening in timber, plywood, and soft board materials.
The round head remains visible for a traditional finish, the slot allows manual adjustment, and the wood thread bites into fibrous material for stable pull-down force. Its advantages lie in a clear installation method, well-defined load path, and good adaptability across different materials and installation spaces.
This product is suitable for wood furniture, door and window hardware, decorative timber parts, crates, and light wood structures. Brass, stainless steel, zinc plating, or black oxide finishes can be adjusted for the final application, balancing cost control, corrosion protection, and assembly consistency.
