Professional Applications & Engineering Value
These thread forming DST screws are specifically engineered for plastic fastening applications where traditional cutting screws may cause material stress or cracking. The 410 Stainless Steel construction provides excellent corrosion resistance while the thread forming technology creates strong, permanent threads in plastic substrates without generating chips or debris. The Phillips pan head design ensures easy installation with standard tools, making them ideal for high-volume assembly operations in electronics enclosures, automotive components, and consumer products. With 16 TPI thread pitch and 0.216" thread diameter, these screws deliver superior pull-out strength and vibration resistance in plastic materials, eliminating the need for additional inserts or reinforcement.
Specification Summary & Compliance
These No. 12 x 1/2" tapping screws feature precise thread forming DST technology with right-hand threading and full threading along the shank. The screws are designed for use with 3/16" drill bits (0.187" diameter) and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 410 Stainless Steel material ensures consistent performance while the standardized dimensions maintain compatibility with industrial fastening requirements for plastic applications.
