Meridyen Chipboard Screw 4.0×70 mm Pack of 200

Meridyen Chipboard Screw 4.0×70 mm (Pack of 200)

Very Thick Structural and Carcass Connection

The Meridyen Chipboard Screw 4.0×70 mm is one of the longest and highest strength fasteners designed for joining materials such as chipboard, MDF, plywood, solid wood, and structural carcasses. Its 4.0 mm diameter offers higher tensile and shear strength compared to standard 3.5 mm screws. The 70 mm length (7 cm) is ideal for providing maximum deep grip, especially when fastening very thick panels (40 mm and above), multiple panel layers (e.g., $18 \text{ mm} + 18 \text{ mm}$ + $10 \text{ mm}$), or thick carcasses that will bear heavy loads. This screw is preferred in industrial furniture and structural wood assembly.

Purpose and Key Features

The main purpose of the Meridyen Chipboard Screw is to fasten the thickest or multi-layered wood materials without splitting them, securing panels, frames, or support structures with increased durability and maximum deep grip.

Screw Type: Chipboard Screw (Phillips Head):

Optimized for wood materials, it features a wide-spaced and deep thread structure. This structure provides a strong and permanent grip in particle boards.

Head Type: Countersunk Head:

The conical shape of the head allows it to be completely embedded into the material when screwed, flush with the surface. This ensures the surface remains flat and provides an aesthetic finish.

Size and Application Area (Deepest Assembly):

4.0 mm Diameter x 70 mm Length: The 4.0 mm diameter offers a stronger body, increasing connection strength. The 70 mm length provides maximum thread grip when attaching a standard 18 mm panel to a very thick carcass (50 mm - 60 mm).

Tip Structure:

The sharp tip structure reduces the need for pre-drilling even in thick materials and supports quick assembly.

Surface Coating:

Usually coated with yellow zinc (chromate) or white zinc. Provides corrosion resistance and aesthetics.

Areas of Use and Sectors

This screw is used in all carpentry, furniture, and structural applications that require the joining of very thick panels, extra deep connections, and heavy-duty strength.

Sector of Use	Application Areas
Heavy-Duty Furniture	Assembly of multi-layered or thick frame furniture (especially three or more layered connections).
Carpentry and Workshop	Mounting panels or other supporting wooden elements to very thick solid wood carcasses (up to 6 cm).
Interior Construction	Maximum secure mounting of very large and heavy cabinets and shelf units to walls with long anchors.
