• Easy installation and removal thanks to the No. 0 Phillips drive and pan head design, allowing for efficient assembly with standard tools.
• Enhanced durability with partially threaded shank and blunt tip, providing controlled penetration and minimizing plastic damage.
• Compliance with industry standards including RoHS 3 and REACH, ensuring safe use in regulated industrial and consumer applications.
• Consistent performance with standardized dimensions (0.06" diameter, 1/2" length) and pan head profile for reliable fit in various plastic assemblies.

Professional Applications & Engineering Value

These 18-8 Stainless Steel TRS tapping screws are engineered to address common challenges in plastic fastening, such as material cracking, thread stripping, and corrosion. The Tri-Lobe shank cross-section and thread-forming design displace plastic material during installation, creating strong, permanent threads that resist loosening under vibration. This makes them ideal for industrial applications in electronics, automotive components, and consumer goods where plastic assemblies require secure, long-lasting fastening. The Phillips drive No. 0 ensures easy torque application, while the rounded pan head provides a flush finish. With 42 TPI precision threading and stainless steel material, these screws offer excellent pull-out strength and environmental resistance, reducing maintenance costs and improving product lifespan.

Specification Summary & Compliance

This product features a thread diameter of 0.06" with approximately 42 threads per inch and a minimum thread length of 3/8". The screw follows standard thread-forming (TRS) specifications with a Tri-Lobe shank and right-hand threading. It is designed for use with a No. 56 drill bit (0.0465" diameter) in plastic materials. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial fasteners.
