Hex Flange Self-Tapping Screws
Hex Flange Self-Tapping Screws are specialized fasteners designed for quick and secure installation in metal, plastic, and wood without requiring pre-drilled holes. The hexagonal flange head with an integrated washer provides improved load distribution and resistance to loosening, making these screws ideal for automotive, industrial machinery, construction, and sheet metal applications.
At Rajal Industries, we manufacture precision-engineered Hex Flange Self-Tapping Screws that conform to DIN and general self-tapping standards, ensuring high tensile strength, optimal thread engagement, and long-term performance.
