उत्पाद वर्णन

Wafer Head Truss Head Self Drilling Screws are advanced fasteners designed for quick, reliable fastening in metalworking and construction. They feature a wide, low-profile head providing strong load distribution, and a self-drilling tip that combines drilling, tapping, and fastening in a single stepmaking them ideal for applications requiring efficiency and durability.

Key Benefits

Fast Installation: The self-drilling tip eliminates the need for pre-drilling holes, saving considerable time in assembly and installation projects.

Large Bearing Surface: Wafer/truss heads provide a wide, stable surface that disperses loads evenly, reducing the risk of damaging softer materials like wood or thin metal sheets.

Smooth, Low-Profile Finish: The truss head sits flush and minimizes snagging or obstruction, which is especially valuable for aesthetic or confined-space installations.

Corrosion Resistance: Typically available with zinc, nickel, or Ruspert coatings, or in stainless steel grades, these screws offer strong resistance to rust and environmental wear.

Versatility: Suitable for joining metal-to-metal, metal-to-wood, and even some plastic assemblies across construction, automotive, and HVAC industries.

Typical Applications

Steel frame construction: Used extensively in residential and light commercial steel structures, including roofing and siding attachment.

Metal sheet fastening: Ideal for fixing metal sheets to steel or wooden substrataoften used in ductwork, electrical assemblies, and false ceiling installations.

General fabrication: Suitable for lath attachment, wall paneling, drywall installations, and other projects requiring strong, discrete fastening.

Usage Guidelines

Select screws based on the thickness and type of materiallonger flutes and tougher drill points are required for thicker or harder substrates.

Use a correct driver and maintain moderate RPM to avoid overheating and potential failure of the drill point.

In corrosive or exterior environments, opt for stainless steel variants or those with robust anti-corrosive coatings.

Engineered for Performance and Strength

These self-drilling screws are manufactured using robust carbon steel and feature a polished, zinc-plated surface for optimal corrosion resistance. The coarse threading and drill point enable swift penetration into steel substrates, while the wide wafer head ensures a stable and secure connection, making them a go-to solution for demanding industrial applications.


Versatile Applications Across Environments

The screws are tailored for both indoor and outdoor use, determined by the type of plating. Their high tensile strength and corrosion protection make them especially suitable for roofing, metal framing, and other steel-to-steel construction tasks in varied weather conditions. Supplied in multiple sizes and conveniently packed for your project needs.
