Professional Applications & Engineering Value

These DST thread forming screws are specifically engineered to address the unique challenges of plastic assembly applications. The thread forming technology creates strong, reliable connections by displacing material rather than cutting it, eliminating chips that could contaminate sensitive components. The black zinc-plated steel construction provides excellent corrosion protection while maintaining the necessary strength for durable fastening. With their fully threaded design and No. 2 Phillips drive, these screws deliver consistent clamping force and easy installation in various plastic materials, from automotive components to electronic enclosures. The precision-engineered 0.138" thread diameter and 19 threads per inch ensure optimal engagement without compromising material integrity, making them ideal for high-volume manufacturing environments where reliability and efficiency are critical.
