Wireforce Zambia manufactures **self-drilling screws**, which are fasteners designed to drill their own hole as they are driven into materials like metal or wood. These screws combine drilling and fastening in one action, eliminating the need for pre-drilling. They are commonly used in roofing, metal framing, and construction projects. Wireforce Zambia ensures high-quality, durable screws with a sharp drill point for efficient and secure installations.
