Modified Design Truss Self-Drilling Screw

Truss Head Shape:

The head of the screw has a truss or conical shape, meaning it is raised and rounded, rather than flat.

This truss head profile allows the screw to sit flush with the surface while providing a relatively low-profile appearance.

Self-Drilling Tip:

The tip of the truss self-drilling screw is designed to drill its own hole as the screw is driven into the material.

This eliminates the need for pre-drilling a pilot hole, making installation faster and easier.

Threaded Shaft:

The shaft of the truss self-drilling screw features threads that allow it to securely grip the material it is fastened into.

The threads typically extend along the entire length of the shaft.

Materials:

Truss self-drilling screws are commonly made from hardened steel, with options for corrosion-resistant finishes like zinc plating or stainless steel.

Applications:

These screws are often used in metal framing, HVAC ductwork, roofing, and other construction applications where a self-drilling feature is beneficial.

The truss head design provides a low-profile, finished appearance compared to traditional hex head or pan head self-drilling screws.

Advantages:

The self-drilling capability allows for faster installation without the need for pre-drilling.

The truss head shape sits flush with the surface, creating a cleaner overall appearance.

The threads along the full length of the shaft provide strong holding power in the material.
