Professional Applications & Engineering Value

These M3.5 TRS tapping screws deliver exceptional value in plastic fastening applications where material integrity is paramount. The thread forming design eliminates the need for pre-tapped holes, reducing assembly time and costs while creating stronger thread engagement in thermoplastic materials. Manufactured from 18-8 stainless steel, these screws resist corrosion in humid or chemical environments, making them ideal for electronic enclosures, automotive components, and consumer products. The Phillips drive system ensures reliable installation torque transfer, while the pan head configuration provides a clean, finished appearance. With full threading along the 30mm length, these metric tapping screws maintain consistent clamping force across the entire engagement area.

Specification Summary & Compliance

This M3.5 x 30mm TRS screw features metric threading with standard pitch of 1.57mm and requires No. 34 drill bit (0.111") for proper installation. The thread forming tapping method creates durable threads in plastic substrates without removing material. Manufactured to industry standards for tapping screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety requirements for industrial use.
