Professional Applications & Engineering Value

These No. 14 x 2" zinc-plated steel tapping screws deliver exceptional engineering value for plastic assembly applications where traditional fastening methods fall short. The DST type thread forming design eliminates the need for pre-tapped holes, reducing assembly steps and labor costs while creating strong, vibration-resistant connections in plastic substrates. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the Phillips No. 3 drive system ensures reliable installation without specialized tools. These plastic fasteners are particularly valuable in electrical enclosures, automotive trim, consumer products, and construction applications where plastic components require durable, long-lasting mechanical fastening solutions that won't strip or loosen under stress.

Specification Summary & Compliance

These tapping screws feature precise dimensional specifications including a 0.242" thread diameter with 15 threads per inch, 2" length, and standard pan head design with 0.492" diameter. Manufactured to ASME B18.6.3 standards, they ensure consistent quality and performance. The thread forming design (DST type) with right-hand threading and blunt tip provides optimal performance in plastic materials when used with recommended No. 7 drill bit (0.201" diameter). The zinc-plated steel construction meets industry requirements for corrosion resistance and durability in various industrial applications.
