Tap-Flex
Thread-Forming Structural Screws are self-tapping fasteners with a thread-forming capability, undergoing dual heat treatment to ensure optimal strength, ductility, and resistance against embrittlement failures. These screws are specifically designed to meet the demanding requirements of critical curtain wall and dissimilar metal applications. They serve as a viable alternative to conventional nut and bolt assemblies and offer an effective solution for blind connections.
