DIN 7982F Countersunk Head Self Tapping Screws

Key Features & Advantages:

1.Countersunk Design for Hidden & Aesthetic Installation
Featuring a standard 90° countersunk head, these screws sink flush with the workpiece surface after installation for a smooth, unobtrusive finish that does not affect subsequent finishing like painting or veneering. Ideal for applications requiring high aesthetics.

2. Dual Drive Options for Versatile Installation
Available in Phillips drive (compatible with standard screwdrivers) and Torx-combination drive (offering higher torque transmission efficiency with reduced slipping, ideal for power bits and automated assembly).

3. Self-Tapping Tip for Fast Installation Without Pre-Drilling
The quenched tip provides high hardness and wear resistance, enabling direct driving into wood, plastic, thin metal sheets, and other substrates without pre-drilling for significantly improved construction efficiency.

4. Full Thread Structure for Secure Engagement & High Pull-Out Strength
The full thread shank features uniform pitch for tight engagement with the substrate, offering high pull-out resistance to prevent loosening and ensure stable, reliable connections.

5. Multiple Surface Treatments for Multi-Environment Compatibility
Available with black oxide, zinc plating, colored zinc, Dacromet, and other finishes for excellent corrosion, wear, and weather resistance, suitable for indoor, outdoor, and mildly corrosive environments.

6. High-Strength Carbon Steel Material for Durability
Made of premium carbon steel (e.g., 1018/1022) with quenched and tempered heat treatment, these screws offer high hardness and toughness, resisting breakage and deformation under long-term loads and alternating stress.

7. Wide Range of Sizes
Available in diameters from #4 to #12 and various lengths to fit different panel thicknesses and installation needs, covering most furniture, renovation, and industrial scenarios.

Common Applications:

•Furniture Manufacturing Industry: Assembly and fixing of panel furniture, solid wood furniture, cabinets, wardrobes, and tables, suitable for handleless designs and high aesthetic requirements.

• Renovation & Indoor Projects: Installation and fixing of ceilings, partitions, door/window frames, and wood veneers, suitable for humid indoor environments.

• Wood Structure & Construction Projects: Connection and reinforcement of wooden houses, wood keels, purlins, and structural wood components, suitable for light to medium-load applications.

• DIY & Craft Projects: Assembly and fixing of models, handmade furniture, and simple storage racks, suitable for wood, plastic, and other substrates.

• Electronics & Electrical Equipment: Internal assembly and fixing of chassis cabinets, electrical enclosures, and communication devices, suitable for plastic/thin metal sheet connections.

• Repair & Renovation Projects: Connection reinforcement in old house renovation, furniture modification, and equipment maintenance, suitable for wood, plastic, and other substrates.

• Other General Scenarios: All wood, plastic, and thin metal sheet connection applications requiring countersunk, self-tapping, and no-pre-drilling features.
