• Reliable Phillips No. 3 drive provides secure tool engagement and reduces cam-out during installation
• Optimized for plastic applications with blunt tip and 16 TPI thread pattern to prevent material cracking and stripping
• Full 3/4" threading ensures maximum grip length and superior holding power in plastic substrates
• Regulatory compliance assurance with RoHS 3 and REACH compliance for safe use in industrial and commercial settings
• Precision compatibility with standard 3/16" drill bits for streamlined installation processes

Professional Applications & Engineering Value

These No. 12 DST thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The 410 stainless steel composition provides excellent corrosion resistance while maintaining the necessary hardness for reliable thread forming. The DST (thread forming) design eliminates the need for pre-tapped holes, reducing installation time and labor costs. The 16 TPI thread pattern and blunt tip work together to displace plastic material without creating stress concentrations that lead to cracking. This makes them ideal for plastic components in automotive trim, electronic enclosures, and consumer products where material integrity is critical. The Phillips drive ensures compatibility with standard industrial tools, while the pan head design provides a low-profile finish suitable for various applications.

Specification Summary & Compliance

These tapping screws feature precise inch system measurements including No. 12 screw size, 3/4" length, and 0.216" thread diameter with 16 threads per inch. The thread forming method follows standard DST specifications for plastic applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant status, ensuring environmental safety and regulatory adherence for industrial and commercial use. The right-hand threading and fully threaded design provide consistent performance across all installation scenarios.
