Meridian Truss Head Screw 6.3×38 mm Pack of 200

Meridyen Trapezoidal Screw 6.3×38 mm (Pack of 200)

Highest Strength in Medium-Thickness Sandwich Panel and Structural Wood Installation

The Meridyen Trapezoidal Screw 6.3×38 mm is a high-strength fastener designed specifically for securing materials such as trapezoidal sheets, corrugated sheets, and light sandwich panels to medium-thickness wood or steel profiles in roofing and facade cladding systems. It features the largest diameter and medium length combination. The 6.3 diameter offers significantly higher tensile and shear strength than all standard screws on the market, maximizing critical connection power. The 38 mm length is ideal for providing a strong, deep, and watertight hold to the carcass when the thickness of the sheet, insulation, and profile is moderate. This screw is designed for structural projects requiring high security and permanence.

Purpose and Key Features

The main purpose of the Meridyen Trapezoidal Screw is to mount thin sheets or panels to the structure with maximum strength, along with a sealing washer, to withstand high wind and load pressures.

Screw Type: Self-Drilling Trapezoidal Screw (Hex Head):

Drill Point (Self-Drilling Screw): The drill point at the end of the screw allows for easy penetration through metal sheets and steel/wood profiles without the need for pre-drilling.

Maximum Strong Diameter (6.3): The 6.3 diameter offers the strongest body among trapezoidal screws, maximizing connection strength, thereby minimizing the risk of breakage and loosening at the connection point.

Head Type: Hex Head:

Suitable for tightening with a socket or wrench, providing 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 ensures water and moisture tightness by pressing against the sheet surface when screwed.

Size and Application Area:

6.3 Diameter x 38 Length: While the 6.3 diameter provides the strongest grip, the 38 length offers ideal depth, especially when securing trapezoidal sheets and light sandwich panels to medium-thickness (approximately 25-30 mm thick) steel or wood frameworks.

Usage Areas and Sectors

This screw is used in all construction, industrial cladding, and assembly applications that require sealing, highest strength, and medium-depth hold.

Product Description

The Meridyen Trapezoidal Screw, with a diameter of 6.3 mm and a length of 38 mm, is a professional product designed to provide maximum strength and sealing in roof and facade installations. With its 6.3 mm diameter, it is the strongest diameter in the trapezoidal screw series. Its self-drilling tip eliminates the need for pre-drilling. The hex head and the special sealing washer underneath ensure a waterproof, strong, and permanent connection. It is zinc-coated for corrosion resistance. In a pack of 200, it is a fundamental and reliable fastener for industrial construction and assembly projects that require medium-depth connections but demand maximum security.
