Design
The truss head is wide and slightly rounded with a low profile, providing a large bearing surface that helps distribute the load and reduces the risk of the screw pulling through the material.
The head features serrations or ridges around its perimeter, which enhance the screw’s gripping power and resistance to loosening due to vibration.
The screw has a drill-like tip that allows it to cut its own hole in the material, eliminating the need for a pre-drilled pilot hole. This makes installation quicker and easier.
The threads are designed to cut into the material, providing a strong and secure hold. The threads usually extend up to the self-drilling tip.
Material
Steel: Most commonly made from hardened steel to provide strength and durability.
Coatings: Often coated with zinc or other corrosion-resistant finishes to protect against rust and extend the screw's lifespan, especially in outdoor or high-humidity environments.
Available in various lengths and diameters to suit different applications and material thicknesses.
Some versions may have additional features like a washer integrated under the head for added load distribution and sealing.
Applications
Construction: Used for securing metal roofing, siding, and other structural components.
HVAC: Commonly used in the installation of ductwork and other HVAC components.
Automotive: Employed in the assembly of body panels and other components.
General Assembly: Suitable for a variety of applications where a secure and easy-to-install fastener is needed.
