Professional Applications & Engineering Value

These No. 12 x 1" stainless steel tapping screws are specifically engineered for plastic assembly applications where reliable fastening is critical. The 18-8 stainless steel material provides exceptional corrosion resistance, making these thread forming screws ideal for environments exposed to moisture, chemicals, or outdoor conditions. The DST (Thread Forming) design creates strong, permanent threads in plastic substrates without creating chips or debris, eliminating the need for pre-tapped holes and reducing assembly time. The Phillips pan head drive system ensures quick installation with standard tools while maintaining a low-profile appearance. These plastic screws are particularly valuable in electrical enclosures, automotive components, and consumer products where vibration resistance and long-term reliability are essential.

Specification Summary & Compliance

These tapping screws feature precise inch system measurements with a No. 12 screw size, 1" length, and 0.216" thread diameter with 16 threads per inch. The thread forming (DST) tapping method creates strong engagements in plastic materials when used with the recommended 3/16" drill bit (0.1875" diameter). Manufacturing complies with industry standards for dimensional accuracy and performance. The products are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring they meet current environmental and safety regulations for industrial use.
