• Excellent thread-forming capability in plastic materials thanks to the tri-lobe shank design, reducing installation torque and preventing material stress
• Reliable and secure fastening achieved through the Phillips No. 0 drive, ensuring consistent installation and minimizing cam-out risks
• Optimized for plastic assembly with a blunt tip and fully threaded design, providing maximum holding power and preventing material damage
• Precision dimensional accuracy with 0.06" diameter and 3/8" length, ensuring consistent performance and interchangeability in automated assembly
• Enhanced environmental compliance meeting RoHS 3 and REACH standards, making them suitable for regulated industries and global supply chains
• Streamlined installation process with recommended No. 56 drill bit (0.0465" diameter), enabling efficient pilot hole preparation and reducing assembly time

Professional Applications & Engineering Value

These 18-8 stainless steel TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications, where material integrity and fastener reliability are critical. The tri-lobe shank cross-section and thread forming design displace plastic material during installation, creating strong, permanent threads without tapping operations. This eliminates the need for separate inserts and reduces assembly steps, while the fully threaded configuration and 42 TPI density ensure maximum engagement and pull-out resistance in brittle or soft plastics. The Phillips drive provides controlled torque application, preventing over-tightening and material cracking. Ideal for electronics enclosures, automotive components, and consumer products, these screws deliver consistent performance in high-volume manufacturing environments.
