Professional Applications & Engineering Value

This M3.63 TRS thread forming screw is specifically engineered for plastic applications, where traditional fasteners may cause cracking or stripping. The tri-lobe shank design and thread forming method displace material to create precise, durable threads without generating chips, reducing cleanup and improving joint integrity. Made from zinc-plated steel, it offers enhanced corrosion resistance for outdoor or humid environments. The Torx Plus IP15 drive ensures maximum torque transfer, minimizing slippage during high-speed assembly in automotive, electronics, and appliance manufacturing. Its fully threaded construction and 1.34mm pitch provide uniform load distribution, making it ideal for securing plastic housings, panels, and components where vibration resistance is critical.

Specification Summary & Compliance

This metric tapping screw features an M3.63 size with 14mm length, 1.34mm approximate thread pitch, and fully threaded tri-lobe shank for thread forming applications. It includes a 7mm pan head with Torx Plus IP15 (T15) drive, ensuring precise torque control. The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for industrial use in plastic materials, with a recommended drill bit size of 1/8" (0.125").
