Professional Applications & Engineering Value

These M3.5 x 16mm 18-8 stainless steel TRS tapping screws deliver exceptional engineering value in plastic assembly applications. The thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, vibration-resistant connections. The Phillips pan head design with No. 1 drive size provides reliable torque transmission and flush seating in plastic components. Manufactured from corrosion-resistant 18-8 stainless steel, these metric screws maintain integrity in humid or chemically challenging environments. The 1.57mm thread pitch and fully threaded configuration ensure maximum pull-out resistance in thermoplastic and thermoset materials, making them ideal for electronics enclosures, automotive trim, consumer products, and industrial equipment where plastic fastening solutions require durability and precision.

Specification Summary & Compliance
