Concrete screws reduced cylindrical head 6-lobe drive

Thread pitch and thread



Concrete screws with a reduced cylindrical head and 6-lobe drive are designed for direct fastening into concrete, solid masonry, and other high-density construction materials. The special high-performance thread allows the screw to cut directly into the material during installation, creating a strong mechanical connection without the need for traditional anchors.
The thread geometry, with a pitch specifically designed for mineral materials, ensures high anchoring capacity, good pull-out resistance, and an even distribution of stresses within the base material. The hardened tip facilitates the start of installation and improves centering accuracy in the pre-drilled hole.
To ensure optimal performance, it is essential to respect the recommended drilling diameter and depth. The hole must be cleaned of dust and debris to guarantee correct screw insertion and achieve a safe and durable fastening over time.


Head type



The reduced cylindrical head is designed to provide a compact and low-profile head while remaining visible on the surface of the material. This head design is particularly suitable for applications where limited head protrusion and controlled dimensions are required.
The 6-lobe drive allows optimal torque transmission, reducing the risk of tool slippage and improving control during installation. This system also enables higher tightening torque compared to traditional drives, increasing the efficiency and reliability of the fastening.

Description and applications


Concrete screws with a reduced cylindrical head and 6-lobe drive are widely used in the construction and installation sectors thanks to their high anchoring capacity and ease of installation.

Typical applications include:


  • fastening brackets and supports to concrete

  • installation of electrical and mechanical systems

  • mounting metal profiles and light structures

  • fixing cable trays, rails, and technical supports
  • light structural applications in the construction sector

Thanks to the combination of a thread specifically designed for mineral materials, a reduced cylindrical head, and a 6-lobe drive, these screws represent a reliable solution for concrete fastening applications requiring high strength, fast installation, and long-term safety.


Material and surface


Concrete screws with a reduced cylindrical head and 6-lobe drive are manufactured from high-strength materials designed to withstand the high loads typical of fastening applications in construction materials.

They are generally available in:


  • Hardened carbon steel with white zinc plating, for standard indoor applications

  • Steel with high-performance anti-corrosion coatings, for increased durability

  • A4 stainless steel or special coatings, for outdoor or particularly aggressive environments

Surface treatments ensure high mechanical strength and good corrosion resistance, even in demanding operating conditions.
