Self-drilling metal screws, commonly known as TEK screws, are high-performance fasteners designed to drill, tap, and fasten in a single operation. Featuring a precision-engineered drill-bit point, these screws eliminate the need for pre-drilling, significantly reducing installation time and labor costs while ensuring a strong, secure fixing.

Manufactured from high-grade carbon steel or stainless steel, self-drilling screws offer excellent strength, durability, and resistance to wear. The sharp, well-defined threads provide maximum holding power in metal substrates, making them ideal for metal-to-metal and metal-to-wood connections. Depending on application requirements, they are available with various head types such as pan head, wafer head, countersunk (CSK), and hex washer head, allowing flexibility for both structural and finishing work.

These screws are widely used in gypsum board installation on metal studs, light and heavy steel framing, sheet-metal fixing, HVAC ducting, roofing systems، و cladding applications. For outdoor and moisture-exposed environments, options with zinc plating, phosphate coating, ruspert coating, or EPDM washers are available to provide enhanced corrosion resistance and long-term performance.

Self-drilling metal screws come in multiple diameters, lengths, and drill-point sizes (TEK #1 to TEK #5), enabling reliable fastening through different metal thicknesses. Their clean drilling action minimizes material damage, ensures accurate alignment, and delivers a professional, long-lasting finish.

Overall, self-drilling metal screws are a time-efficient, cost-effective, and dependable fastening solution for construction, interior finishing, and industrial projects where speed, strength, and precision are essential.
