Professional Applications & Engineering Value

These 410 stainless steel DST tapping screws are engineered specifically for plastic assembly applications where material integrity and long-term performance are critical. The thread-forming design eliminates the need for separate tapping operations by displacing plastic material to create strong, load-bearing threads that resist stripping and back-out. The Phillips flat head with 82° countersink angle ensures flush mounting while the fully threaded configuration provides maximum engagement in various plastic thicknesses. This combination addresses common industrial challenges including vibration resistance, material compatibility, and assembly efficiency in plastic component manufacturing, electronic enclosures, automotive trim, and consumer products where reliable fastening in thermoplastic and thermoset materials is essential.

Specification Summary & Compliance

These No. 4-24 x 1/2" DST tapping screws feature standard inch measurements with Class 2A thread tolerances and are manufactured to industry standards for thread-forming screws in plastic applications. The specifications include a 0.112" thread diameter with 24 threads per inch, blunt tip design, and round shank cross-section. Compliance is maintained with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and market acceptability for industrial and commercial use across global supply chains.
