Professional Applications & Engineering Value

These No. 8 x 1/2" 410 stainless steel DST thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming design eliminates chip formation during installation, preventing contamination and ensuring clean, reliable fastening in delicate plastic components. The fully threaded configuration provides maximum engagement along the entire fastener length, significantly enhancing pull-out strength in plastic materials. The pan head with Phillips drive offers a balanced profile that distributes clamping force effectively while maintaining easy installation access. These industrial screws are particularly valuable in applications requiring repeated disassembly and reassembly, as the formed threads maintain their integrity through multiple cycles, making them ideal for plastic assembly in electronics enclosures, automotive components, and consumer products where reliability and corrosion resistance are critical.

Specification Summary & Compliance

These thread forming screws feature precise dimensional accuracy with a 0.164" thread diameter and 18 threads per inch configuration. The DST (Thread Forming) tapping method ensures consistent performance in plastic materials when used with the recommended No. 29 drill bit (0.136" diameter). The screws maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for global industrial applications requiring environmental and safety standards adherence. The right-hand threading and fully threaded design provide reliable fastening performance across various plastic assembly requirements.
