What Are Self-Drilling Screws?

Self-drilling screws, often referred to as Tek screws, are high-performance fasteners with a built-in drill point at the tip. This drill point allows them to cut their own hole while fastening, combining drilling and driving in one step. The advantage is efficiency: contractors eliminate the need for pre-drilling, saving valuable time on job sites while reducing overall labor costs and minimizing wear on drill bits.

Once the screw penetrates the surface, precision-engineered threads immediately engage with the material, creating a strong and lasting hold. This combination of speed and holding power makes self-drilling screws one of the most versatile fasteners used in construction, manufacturing, automotive, HVAC, and more.

South Coast Fasteners, Inc. supplies Strong-Point® self-drilling screws in a complete range of diameters, lengths, head styles, and protective finishes. Whether your project involves structural steel, roofing, HVAC ducts, or wood-to-metal connections, Strong-Point® provides a fastening solution designed for lasting performance.

Key Features of Self-Drilling Screws

Built-In Drill Point

The integrated drill tip is the defining feature of self-drilling screws. By combining the drilling and fastening action into one step, these screws significantly cut down installation time. They also ensure consistency in hole size and placement, which reduces installation errors and ensures uniform fastening across projects.

High-Strength Steel Construction

Strong-Point® self-drilling screws are manufactured from hardened, high-tensile steel. This gives them the ability to penetrate heavy-gauge steel and maintain structural integrity under demanding loads. Their durability makes them a dependable choice in environments where failure is not an option.

Corrosion Resistance

Many self-drilling screws feature corrosion-resistant finishes such as zinc plating. These coatings protect against rust and environmental damage, allowing them to perform in both indoor and outdoor environments. This makes them suitable for roofing, siding, fencing, and other projects where weather exposure is a concern.

Precision Threading

Threads are engineered to engage materials smoothly and hold securely, even under vibration, shifting, or temperature change. Strong-Point® offers different thread designs to maximize grip in thin sheet metal, heavy steel, or mixed-material assemblies.

Variety of Head Styles

Hex washer heads, pan heads, and flat heads are all available, allowing professionals to select the fastener that best matches both appearance and performance needs. This variety ensures compatibility across multiple trades, from structural work to finishing projects.

Applications of Self-Drilling Screws

Metal Roofing and Siding

Self-drilling screws are the go-to choice for fastening metal roofing and siding panels. Their drill points penetrate steel and wood framing with ease, while the threads provide a weather-tight grip that resists leaks and wind uplift. Contractors value their ability to deliver long-lasting protection against the elements.

Steel Fabrication

Fabrication shops and structural steel contractors depend on self-drilling screws for fastening beams, supports, and brackets. By eliminating pre-drilling, workers save time and increase productivity on projects ranging from warehouses to commercial buildings.

HVAC Installations

Duct systems, vents, and HVAC equipment all require fast, secure fastening. Self-drilling screws pierce sheet metal quickly, ensuring ducts stay in place under vibration, pressure, and temperature fluctuations. Their strength and corrosion resistance make them ideal for long-term HVAC performance.

Electrical and Plumbing

Installers often use self-drilling screws to attach conduit straps, junction boxes, pipe clamps, and fixtures to steel or wood framing. Corrosion-resistant finishes ensure they hold up in damp basements, exterior settings, or areas exposed to condensation.

Automotive and Machinery

Self-drilling screws are used for attaching body panels, support brackets, and structural components in automotive manufacturing and repair. Their ability to drill directly into steel makes them indispensable in high-volume assembly lines and heavy equipment maintenance.

Wood-to-Metal Connections

In fencing, decking, and outdoor construction, self-drilling screws are often used to fasten wood securely to metal posts or frames. The drill point penetrates the steel, while the threads pull wood tight for a secure, lasting connection.
