Meridyen Trapezoidal Screw 5.5×38 mm (Pack of 200)
Superior Strength for Medium-Thickness Structural Wood and Metal Connections
The Meridyen Trapezoidal Screw 5.5×38 mm is a high-strength fastener designed specifically for securing materials such as trapezoidal sheets, sandwich panels, and corrugated sheets in roofing and facade cladding systems to medium-thickness wooden or metal frameworks. Its 5.5 diameter offers higher tensile and shear strength compared to the standard 4.8 diameter, increasing connection security under wind and load pressure. The 38 mm length is ideal for providing reliable grip depth and sealing at the junction of the sheet and framework. Its self-drilling (smart screw) design enables quick and efficient installation, making it preferred in professional construction projects.
Purpose and Key Features
The primary purpose of the Meridyen Trapezoidal Screw is to mount roofing and facade elements exposed to heavy loads or those requiring attachment to thicker structural elements, along with a sealing washer, for extra strength and durability.
Self-Drilling Tip (Smart Screw): The drill bit at the tip of the screw allows easy penetration through metal sheets and steel/wood profiles without the need for pre-drilling.
Extra Strong Diameter (5.5): The 5.5 diameter, with its thicker body, offers higher resistance to wind loads and thermal movements compared to standard screws.
Head Type: Hex Head:
Suitable for tightening with a socket or wrench, ensuring a complete and reliable fastening with high torque.
Sealing Feature (Washer):
The screw typically comes with an EPDM or rubber washer under the head. This washer, when tightened, presses against the sheet surface, guaranteeing water and moisture impermeability, which is critical for outdoor applications.
Size and Application Area:
5.5 Diameter x 38 Length: The 5.5 diameter provides a strong grip, while the 38 length offers sufficient depth for securing trapezoidal sheets or sandwich panels to medium-thickness (approximately 25-30 mm thick) wooden or light steel frameworks.
Usage Areas and Sectors
This screw is used in all construction, cladding, and industrial assembly applications that require sealing, high strength, and rapid installation.
