Square Head Phillips Head Chipboard Screw furniture self-tapping screws cross-slot wood screws

This series of colored zinc carbon steel self-tapping wood screws are specially designed for wood connection scenarios and are dedicated to non-pre-drilled fastening. They cover two categories: the conventional model with full-threaded cross-slot and the extended model with inner square half-thread. They can be compatible with various installation tools, wood thicknesses, and working conditions.

The product is made of high-quality carbon steel and is formed as a single piece. Its surface undergoes an environmentally friendly zinc coating treatment. The pointed tail self-tapping structure has high hardness and sharp cutting edge. It can directly penetrate various types of wood such as solid wood, density board, and anti-corrosion wood without the need for pre-drilling. The conical head design allows it to fully sink into the surface of the workpiece after installation, without any protrusions or scratches, and does not affect the appearance. The thread is processed by a precise rolling process, ensuring tight engagement and preventing slippage or loosening. It also balances installation efficiency, rust prevention performance, and connection stability, making it a universal core component for furniture manufacturing, woodworking decoration, and wood structure construction.

Core structure: Sharp tail self-tapping + conical design. Available in two thread types: full thread (cross style) / half thread (inner square extended style).

Drive type: Two options available - cross slot (universal style) and inner square slot (anti-slip style). Suitable for different installation tools.

Material and coating: High-quality carbon steel base material. Surface undergoes eco-friendly colored zinc passivation treatment, preventing rust and corrosion, and complies with RoHS environmental standards.

Specification coverage: Complete thread specifications of M3.5, M4, M5, M6. Length range is 16mm - 100mm, suitable for different wood thicknesses.

Performance: High hardness, sharp tail with strong penetration ability. Threaded connection is tight and anti-loosening. Colored zinc coating is resistant to salt fog, moisture, and does not rust easily.

Installation compatibility: No pre-drilled holes required. Compatible with regular screwdrivers / square bits. Directly compatible with various types of wood, no additional accessories needed.

Furniture manufacturing field: Assembly of panel / solid wood furniture such as wardrobes, cabinets, desks and chairs, bed frames, shoe cabinets, etc. The cross model is suitable for regular boards, and the extended model is suitable for solid wood thick boards. It is crack-resistant and loosening-preventive. After installation, the surface is flat and beautiful, without affecting the appearance of the furniture.

Woodworking decoration scenarios: Fixation of wooden keels, floors, wall panels, and ceiling wooden components in interior decoration. Non-pre-drilled installation is highly efficient. The zinc coating is suitable for humid spaces such as kitchens and balconies to avoid rust-induced structural loosening.

Outdoor wooden structure construction: Construction of anti-corrosion wooden platforms, wooden houses, wooden walkways, and garden fences. The extended model is suitable for thick anti-corrosion wood boards. The semi-teeth design reduces wood cracking. The anti-rust coating resists outdoor wind and rain, ultraviolet corrosion, and extends the service life of the wooden structure.

Woodworking DIY and handicrafts: Handmade models, wood art ornaments, and assembly of small wooden components. The sharp tail is easy to drill into, and the threaded bite is stable. It is suitable for various hand tools, and beginners can also complete the installation easily, meeting the DIY requirements of different wood thicknesses.

Industrial packaging scenarios: Fixation of wooden boxes, pallets, and wooden packaging boxes. Low cost, fast installation, suitable for batch production and transportation needs, anti-loosening and anti-falling off, ensuring the safety of goods transportation.

No pre-drilling installation, significantly improved efficiency

The pointed tail self-drilling tip is hardened, with high hardness and low cutting resistance. It can directly drill into various types of wood without the need for pre-drilling and tapping. One process completes the installation, increasing the efficiency by more than 50% compared to traditional wood screws, especially suitable for batch furniture assembly and decoration construction scenarios.

Color zinc coating protection, rust-resistant and durable without failure

The surface adopts an environmentally friendly color zinc passivation process, forming a dense anti-rust passivation film. The salt spray test duration can reach over 500 hours. It can effectively resist moisture, water vapor, and mild acid-base corrosion. It is suitable for kitchen and bathroom furniture, outdoor anti-corrosion wooden platforms, etc., and does not rust or loosen over a long period of use, significantly reducing maintenance costs.

Dual drive + dual threads, suitable for all scenarios of wood demand

Cross-slot full-thread model: Suitable for regular cross screwdrivers, with strong versatility. The full-thread covers the shaft, has a large biting area, and is more stable in fixation, suitable for thin boards, density boards, and other regular furniture scenarios;

Inner square half-thread extended model: Suitable for special square drill bits. During installation, it prevents slipping and loosening, and the torque transmission is more stable. The half-thread design (the front half is self-drilling thread + the rear half is a smooth rod) reduces the resistance when inserting thick wood, avoids wood cracking, and is suitable for high-strength installation scenarios such as thick wood boards and anti-corrosion wooden columns.

Sunk head flat design, balancing tightness and aesthetics

The precise cone-shaped sunk head design allows the screw head to fully sink into the wood surface after installation, without protrusions or hand-scratching. No additional grinding treatment is required, which does not affect the flatness of the workpiece surface. Suitable for furniture and decoration scenarios that require aesthetic appearance.

Integrated molding process, stable strength without slippage

The screw body adopts cold forging integrated molding technology, without joint welds. The rod body has high strength and is less likely to break. The threads are processed by CNC rolling technology, with regular tooth shapes and strict tolerance control, smooth biting without jamming. It can maintain good locking performance after repeated assembly and does not slip or disengage easily.
