Professional Applications & Engineering Value

These M4 TRS plastic tapping screws are engineered specifically for plastic assembly applications where reliable fastening and material integrity are critical. The thread forming design creates 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 flanged screws provide excellent corrosion resistance while the T20 Torx drive ensures maximum torque transmission without stripping. The integrated flange distributes clamping force over a wider area, preventing plastic deformation and material damage. These fully threaded screws with 1.79mm pitch deliver superior pull-out resistance in thermoplastics, composites, and other plastic materials commonly used in automotive, electronics, and consumer product manufacturing.
