Meridian Drill Bit Screw YHB 4.8X25 (8,000 Pieces)

Meridian Drill Bit Screw YHB – 4.8x25 mm (8,000 Pieces per Box)

Meridian Drill Bit Screw YHB, 4.8x25 mm in size, is a professional fastening element that can be screwed directly into metal and wooden surfaces without pre-drilling. The star countersunk head (YHB) design allows it to sit flush with the mounting surface, providing a smooth and aesthetic finish. The 25 mm length provides secure grip in thicker materials compared to 19 mm and 22 mm models. The drill bit drills into the material, creating its own thread, significantly reducing working time and cost. This product is sold in boxes of 8,000 pieces, making it ideal for wholesale purchases, factory stock, and mass production.

What is a Drill Bit Screw? What are its Advantages?

• No Pre-Drilling Required: The drill bit drills into the material, creating its own thread, eliminating the need for separate drill bits and drilling operations.
• Time & Cost Savings: It drills and screws in one step, reducing working time by up to 50%.
• Star Countersunk Head (YHB): The screw head sits flush with the mounting surface, providing a smooth, aesthetic, and secure finish.
• High Grip Strength: The 25 mm length provides deeper thread penetration, minimizing the risk of loosening.
• Wholesale Cost Advantage: The 8,000-piece box reduces the unit cost in mass production and large projects.

Areas of Use

• Steel Construction: Thick profile joining, sheet cladding, frame mounting
• Roofing & Cladding: Trapezoidal sheet, sandwich panel, gutter mounting (multi-layered)
• Furniture Production: Metal-wood joints, shelving systems, modular furniture
• General Industrial: Machine mounting, maintenance, medium-heavy construction
• Workshop & DIY: Special projects, prototype production, repairs

Frequently Asked Questions

What does "YHB" mean?

YHB stands for "Star Countersunk Head". The screw head has a star (Phillips) drive profile and a countersunk form, allowing it to sit flush with the mounting surface, providing an aesthetic and secure connection.

Which bit should be used?

For 4.8 mm diameter drill bit screws, a PH2 star bit is usually recommended. Choosing the correct bit prevents damage to the screw head and optimizes torque transfer.

What advantage does the 25 mm length provide?

The 25 mm length provides 6 mm more penetration than the 19 mm and 3 mm more than the 22 mm. This means stronger grip in thick metal sheets/profiles (5–6 mm) and multi-layered wood-metal joints. For thin to medium sheets, 19–22 mm may be sufficient.

Why is the box quantity different from other models?

The 25 mm screws are longer and heavier, so they are packaged 8,000 pieces per box (19 mm: 12,000, 22 mm: 9,000). Consider this difference in logistics planning and inventory management.

What is the difference between a drill bit screw and a standard screw?

Standard screws require pre-drilling, while drill bit screws create their own hole. This significantly reduces working time and cost, especially in metal applications, and provides quick mounting in wood applications.
