Professional Applications & Engineering Value

This No. 4 TRS thread forming screw delivers exceptional value in plastic assembly applications where material integrity and long-term reliability are critical. The 18-8 Stainless Steel composition provides inherent corrosion resistance, eliminating concerns about environmental degradation in industrial settings. The innovative Tri-Lobe shank design and thread forming action create strong, permanent threads in plastic substrates without generating chips or debris that could compromise electronic components. With 20 TPI thread pitch and blunt tip configuration, this Phillips drive screw ensures controlled insertion and minimizes the risk of plastic material splitting or stress cracking. The pan head style offers a low-profile finish while providing adequate bearing surface for secure fastening in plastic enclosures, automotive trim components, and consumer electronics assemblies.
