Professional Applications & Engineering Value

These No. 3 TRS thread forming screws deliver exceptional value in plastic assembly applications where material integrity is paramount. The Tri-Lobe shank cross-section and thread forming design create strong, permanent threads in plastic substrates without generating chips, eliminating contamination risks in sensitive electronic or medical assemblies. Manufactured from 18-8 stainless steel, these fasteners resist corrosion in humid or chemically challenging environments while maintaining their mechanical strength. The combination of Phillips drive and rounded pan head provides both installation efficiency and a finished appearance, making these tapping screws ideal for consumer products, automotive components, and electrical enclosures where reliability and aesthetics matter equally.

Specification Summary & Compliance
