Meridyen BULDEX Screw 7.5x150 mm 100-Pack

Meridyen BULDEX Screw 7.5×150 mm (Pack of 100)

Fastenings Requiring Maximum Depth and Structural Strength

In the construction industry, particularly in facade installations, establishing a reliable connection to the main structure by penetrating beyond thick insulation layers or large gaps is of vital importance. For such applications requiring very deep and high load-bearing capacity, traditional fastening methods may be insufficient. The Meridyen BULDEX Screw 7.5×150 mm, with its impressive 150 mm length, the practicality of anchor-free installation, and high strength, meets the most demanding fastening needs.

Purpose and Key Features

The primary purpose of the Meridyen BULDEX Screw is to secure structural elements such as PVC, aluminum, or wood to hard construction materials like concrete, brick, and stone at the deepest point and with maximum strength, without using anchors, by passing through extra thick materials or gaps between thick insulation layers and the wall.

Screw Type: Anchor-Free Concrete Screw (Buldex/Frame Anchor):

Thanks to its hardened steel structure, it does not require an anchor. It creates its own thread within the hard building material by entering the pre-drilled pilot hole, ensuring the screw is firmly anchored to the wall/floor.

Size and Application Area:

7.5 mm Diameter x 150 mm Length: This longest size, in addition to the high tensile strength provided by its 7.5 mm thick diameter, is specifically designed to reach the main wall behind thick exterior insulation (cladding) or to fasten very thick profiles. This length offers maximum security against vibrations and loads.

Special Thread Design (Dust Channel):

Special channels on the screw discharge dust generated during screwing, preventing jamming. This allows even a long screw like 150 mm to reach full depth with high speed and reliability.

Head Type and Drive:

Typically features a Countersunk Head (for a flush finish) and a T30 Torx drive recess. The T30 Torx provides full control even when using high torque with a screw of this length.

Surface Coating:

Protected with a special zinc coating to increase longevity, outdoor use, and corrosion resistance.

Areas of Use and Sectors

This extra-long Buldex screw is used in the most demanding fastenings where structural integrity and deep connection are essential.

Application Sector	Application Areas
Facades and Insulation	Deep fastening of window/door frames to the main wall in buildings with thick insulation (cladding) layers.
Construction and Heavy Assembly	Fastening thick (e.g., more than 10 cm thick) construction profiles or load-bearing metal elements to rigid structures.
Structural Reinforcement	Mounting consoles, heavy-duty suspension systems, and machine feet to concrete floors/walls at maximum depth.
Aluminum/PVC Systems	Secure connection of very large and heavy window/door systems to the main structure against wind loads.

Product Description

The Meridyen BULDEX Screw, with a diameter of 7.5 mm and a length of 150 mm, is a professional heavy-duty fastener that offers the highest level of fastening power in hard construction materials such as concrete, brick, and stone, thanks to its anchor-free design. Its 150 mm length guarantees the strongest and deepest connection to the main structure, especially in challenging assembly areas with thick insulation layers or large gaps. Its special thread design and dust channels prevent the screw from jamming, ensuring high gripping power and fast installation. This T30 Torx head screw is an indispensable solution for all construction and facade installation jobs requiring high volume, structural strength, and maximum security.
