Professional Applications & Engineering Value
These No. 3 TRS tapping screws are engineered to address common challenges in plastic fastening, such as material cracking and poor retention. The thread forming design with a tri-lobe shank creates strong, permanent threads in plastics, minimizing stress and providing excellent resistance to vibration and pull-out forces. Made from zinc-plated steel, they offer durability against corrosion, ideal for electronics enclosures, automotive trim, and consumer appliances. The Phillips drive ensures easy installation with standard tools, reducing assembly time and improving productivity in industrial settings where precision and reliability are critical.
Specification Summary & Compliance
This product adheres to standard inch measurements with a thread diameter of 0.099" and length of 5/16", featuring a Class 2A thread fit for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability. The screw is designed for use with a No. 43 drill bit (0.089" diameter) and follows typical thread forming specifications for plastic applications, providing reliable fastening without additional tapping requirements.
