Hex Flange Head Self-Tapping Screws with Wood Thread

Thread and Pitch


Hex flange head self-tapping screws with wood thread are designed to ensure fast and secure fastening in wood and wood-based materials. The wood-specific thread, characterized by a wider and deeper pitch, allows the screw to penetrate the material easily and form its own seating during installation.
The pointed tip facilitates initial penetration and proper centering of the screw, reducing the need for pre-drilling in most applications. This thread geometry provides excellent grip in wood, good pull-out resistance, and a stable, long-lasting fastening over time.
They are particularly suitable for fastening solid wood elements, chipboard panels, MDF, plywood, and other wood-based materials.


Head Type


The hex head with integrated flange (washer head) increases the bearing surface during tightening, distributing the clamping force evenly across the material. The integrated flange acts as a built-in washer, improving fastening stability and reducing the risk of damaging the wood surface.
The hex head also allows the use of standard wrenches, sockets, or automated tools, ensuring optimal torque transmission and fast, efficient tightening even in professional applications.

Description and Applications

Hex flange head self-tapping screws with wood thread are widely used in carpentry and construction sectors due to their strength and ease of installation.

Typical applications include:

  • wooden structures and carpentry

  • timber construction and assemblies

  • fastening of panels and boards

  • window and door frame structures

  • installation work in construction and industrial environments

Thanks to the combination of wood-specific thread, hex head, and integrated flange, these screws represent a reliable solution for fast, strong, and durable fastening, while ensuring simple installation and long-term stability.


Material and Surface


Hex flange head self-tapping screws for wood are available in different materials and surface finishes to suit various operating conditions:

  • Hardened carbon steel with white zinc plating, for standard applications with good corrosion resistance

  • Zinc-plated steel with additional protective treatments, for increased durability

  • Stainless steel A2, ideal for humid environments or indoor applications exposed to moderate corrosion

  • Stainless steel A4, recommended for outdoor or highly aggressive environments

The quality of the materials ensures high mechanical performance and excellent corrosion protection even in demanding operating conditions.
