Professional Applications & Engineering Value

These No. 12 x 1/2" stainless steel tapping screws deliver exceptional value in plastic assembly operations where material integrity and long-term performance are critical. The thread forming design (DST type) eliminates the need for separate tapping operations while creating strong, vibration-resistant connections in plastic substrates. The 18-8 stainless steel composition provides excellent corrosion resistance, making these Phillips pan head screws ideal for applications exposed to moisture, chemicals, or outdoor environments. The fully threaded construction with blunt tip minimizes stress concentration points that can lead to plastic cracking, while the standardized 3/16" drill bit size ensures quick, accurate installation across production runs. These features combine to reduce assembly time, improve joint reliability, and extend service life in plastic fastening applications across electronics enclosures, automotive components, and industrial equipment.

Specification Summary & Compliance

These tapping screws feature precision Class 2A thread tolerances with 0.216" thread diameter and 16 threads per inch, manufactured to industry standards for consistent performance. The DST thread forming technology creates permanent threads in plastic materials without chip removal. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence. The screws are designed for use with standard 3/16" (0.1875") drill bits and feature right-hand threading with fully threaded construction for maximum holding power in plastic applications.
