Meridian Drill Bit Screw YHB 4.8X22 (9,000 Pieces)

Meridian Drill Bit Screw YHB – 4.8x22 mm (9,000 Pieces per Box)

Meridian Drill Bit Screw YHB, 4.8x22 mm in size, is a professional fastening element that can be screwed directly into metal and wood 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 22 mm length provides secure grip in thicker materials compared to 19 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 9,000 pieces, making it ideal for wholesale purchases, factory stock, and mass production.

Technical Specifications

4.8x19 mm vs 4.8x22 mm: Which to Choose?

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 drilling and hole creation.
• 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 22 mm length provides deeper thread penetration, minimizing the risk of loosening.
• Wholesale Cost Advantage: The 9,000-piece box reduces unit cost in mass production and large projects.

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 drill bit should be used?

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

What advantage does the 22 mm length provide?

The 22 mm length provides 3 mm more penetration than the 19 mm length. This means stronger grip in medium-thickness metal sheets/profiles (4–5 mm) and wood-metal combinations. For thin sheets, 19 mm may be sufficient.

Why is the box quantity different from the 19 mm model?

The 22 mm screws are longer and heavier, so they are packed in boxes of 9,000 pieces (compared to 12,000 pieces for the 19 mm model). 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 assembly in wood applications.
