Superior Strength for Very Long-Range Metal and Thick Carcass Fixing
Meridyen YHB (Countersunk Head) Self-Drilling Screw 4.8×38 mm is a fastener designed for attaching materials such as thin metal sheets, sheet metal panels, PVC window and door profiles, and light steel profiles to each other or to much thicker metal/wood surfaces. It features an extra-long length and a 4.8 diameter, one of the strongest diameters. The 4.8 diameter offers much higher tensile and shear strength compared to standard thin diameters, ensuring maximum safety even in critical structural connections. The 38 length (3.8 cm) is ideal for deep fixing of support steel sheets placed inside PVC profiles to thick wood or concrete carcasses, or for long-range installations made through thicker insulation materials. Its self-drilling (smart screw) structure completely eliminates the need for pre-drilling.
Purpose and Key Features
The main purpose of the Meridyen YHB Self-Drilling Screw is to join thick parts or panels with high speed and minimum effort, extra deep and securely, flush with the surface.
Screw Type: YHB Self-Drilling Screw (Smart Screw):
Drill Point: The drill point at the tip of the screws allows for easy penetration through metal sheets and profiles up to 2-3 mm thick without requiring pre-drilling.
Countersunk Head (YHB): The underside of the head is flat, but the top surface is slightly domed. This design ensures the screw is flush with the surface it is attached to, providing a smooth and aesthetic finish.
Strong Diameter (4.8): The 4.8 diameter offers high torque and connection strength even for the most demanding applications.
Size and Application Area:
4.8 Diameter x 38 Length: While the 4.8 diameter provides a strong grip, the 38 length is designed for applications requiring extra-long connection depth. This is especially important for fixing metal to thick structural elements.
Surface Coating:
Typically zinc-coated to provide protection against rust and corrosion.
Usage Areas and Sectors
This screw is used in all metalworking, joinery, and construction applications requiring fast fastening, highest strength, and very long connection depth.
| Usage Sector | Application Areas |
| PVC and Aluminum Joinery | Fixing steel reinforcement sheets, placed inside windows and doors, through PVC profiles to thick frames or walls. |
| Light Steel Construction | Deep fixing of thin metal sheets or panels to thicker box sections and other steel frameworks. |
| Construction and Insulation | Mounting metal cladding or auxiliary profiles to the load-bearing carcass over thicker insulation materials (e.g., 15-20 mm thickness). |
| Special Assembly Works | Secure and permanent attachment of metal to much deeper wooden or structural elements. |
Product Description
The Meridyen YHB Self-Drilling Screw, with a 4.8 diameter and 38 length, is specifically designed for much deeper and more reliable joining of PVC joinery and thick structural elements. Its 4.8 diameter provides the highest level of strength. Thanks to its self-drilling structure, it eliminates the need for pre-drilling and shortens installation time. The countersunk head (YHB) ensures the screw is flush with the surface after installation, creating an aesthetic and neat appearance. Its zinc coating enhances corrosion resistance. With a pack of 500, it is an essential fastener for high-volume, deep connection-requiring professional metal assembly jobs.
