• Versatile pan head design offering a low-profile, rounded finish suitable for various plastic assembly applications.

Professional Applications & Engineering Value

These 18-8 stainless steel TRS plastic tapping screws address critical challenges in plastic assembly operations where traditional fasteners fail. The thread forming design with 32 TPI precision creates strong, load-bearing threads in plastic substrates without generating chips that could compromise electronic components or fluid systems. The tri-lobe shank cross-section provides superior resistance to vibration-induced loosening, while the blunt tip ensures proper alignment and prevents material cracking during installation. Ideal for plastic enclosures, automotive trim components, and consumer electronics assemblies, these screws deliver consistent performance in applications requiring corrosion resistance and reliable long-term fastening integrity.

Specification Summary & Compliance

This No. 1 x 1/4" plastic tapping screw features Class 2A thread tolerances with fully threaded right-hand orientation and TRS (Thread Rolling Screw) specifications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction-free use in global markets. The pan head style with standard rounded profile and Phillips No. 0 drive maintains industry-standard installation compatibility.
