Our Key Self-Drilling Screw Products:
To meet the demands of any project, we offer a variety of head types, with three of our most popular being:
- Hex Head Self-Drilling Screws: With a hexagonal head for high-torque driving with a wrench or socket, these are the industry standard for roofing and heavy-duty applications where strong clamping force is required.
- Wafer Head Self-Drilling Screws: Featuring an extra-wide, low-profile head, our Wafer Head screws are perfect for attaching thin panels and cladding, providing a large bearing surface to prevent pull-through without a bulky finish.
- CSK (Countersunk) Head Self-Drilling Screws: Designed to sit flush with the surface, our CSK Head screws provide a clean, snag-free finish, ideal for applications where aesthetics and a smooth surface are critical.
- Pan Head Self-Drilling Screws: A highly versatile option, our Pan Head screws feature a slightly rounded head with a flat bearing surface, providing reliable clamping force for a wide variety of general assembly tasks in metal and other materials.
- Oval Head Self-Drilling Screws: Combining functionality with a finished look, our Oval Head screws have a decorative, countersunk design that sits slightly raised on the material surface. They are an excellent choice for visible fastening points where a more aesthetic appearance is desired.
- Mushroom Head Screw: With its extra-wide, low-profile dome, the Mushroom Head screw is designed to provide a large bearing surface, making it ideal for securing thin or soft materials without risk of pull-through. Its smooth finish also provides an aesthetic, snag-free surface.
All THV self-drilling screws are manufactured from high-quality carbon steel or stainless steel and are available with advanced coatings (e.g., Zinc, Dacromat, Ruspert) for superior corrosion resistance. Produced in strict adherence to international standards like DIN 7504, ISO, and ASME, our screws guarantee consistent performance and long-term durability.
Key Applications: Our self-drilling screws are indispensable in applications requiring fast and reliable metal-to-metal or metal-to-wood fastening:
- Roofing & Cladding: Securely fastening metal roofing and wall panels to steel structures.
- Steel Frame Construction: Assembling light to medium-gauge steel frames and trusses.
- HVAC & Electrical: Mounting ductwork, brackets, and electrical components.
- General Manufacturing: A wide range of assembly tasks in automotive and machinery production.
Engineered for maximum efficiency, THV Fasteners’ self-drilling screws are the ultimate all-in-one solution that drills its own hole and taps its own threads in a single, seamless action. Featuring a hardened drill-bit point, these screws eliminate the need for pre-drilling, dramatically reducing installation time and labor costs while ensuring a perfectly aligned and secure connection.
