Professional Applications & Engineering Value

These No. 2 zinc-plated steel tapping screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The specialized DST thread forming technology eliminates the need for pre-tapped holes, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the Phillips drive system ensures efficient installation with standard tools. Particularly valuable in plastic component manufacturing, these screws prevent material cracking and stripping common with standard screws, making them ideal for electronics enclosures, automotive trim, and consumer products where reliable plastic fastening is critical to product integrity.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including 0.086" thread diameter, 32 TPI thread pitch, and 3/8" length with full threading. The manufacturing process adheres to ASME B18.6.3 standards ensuring consistent quality and dimensional accuracy. The zinc-plated surface treatment provides corrosion resistance while maintaining the mechanical properties of steel. These DST tapping screws are designed for use with No. 50 drill bits (0.07" diameter) in plastic materials, providing optimal hole size for effective thread forming without material stress.
