Professional Applications & Engineering Value

These No. 10 zinc-plated steel TRS tapping screws deliver exceptional engineering value in plastic assembly applications where material integrity and long-term performance are critical. The thread forming design with tri-lobe shank cross-section displaces plastic material rather than cutting it, creating zero clearance threads that resist loosening from vibration and thermal cycling. This approach eliminates the need for pre-tapped holes, reducing assembly time and labor costs while providing superior holding power in thermoplastics and other plastic substrates. The combination of zinc-plated corrosion protection and Phillips drive compatibility makes these screws ideal for electrical enclosures, automotive plastic components, consumer products, and industrial equipment where reliable fastening in plastic materials is essential for product durability and safety.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including No. 10 screw size, 1-1/2" length, 0.19" thread diameter, and 14 threads per inch. The TRS (Thread Rolling Screw) design with tri-lobe shank and blunt tip ensures proper thread formation in plastic materials without chip creation. Manufacturing complies with industry standards for inch system fasteners, while environmental compliance is maintained through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in various industrial and commercial applications.
