Professional Applications & Engineering Value
These black corrosion-resistant steel Torx Plus tapping screws are engineered specifically for creating strong, permanent threads in aluminum, brass, and copper components without requiring pre-tapped holes. The Tri-Lobe shank cross-section displaces material efficiently during installation, forming precise UNC 1/4"-20 threads that resist vibration loosening and provide superior pull-out strength. The Torx Plus IP30 drive system delivers exceptional torque transfer, eliminating cam-out issues that can damage screw heads and compromise assembly integrity. This combination of thread-forming technology and advanced drive design makes these screws ideal for high-volume manufacturing, electrical enclosures, and metal fabrication where reliable fastening in soft metals is critical.
Specification Summary & Compliance
This 1/4"-20 Torx Plus tapping screw features UNC coarse threading with standard Class 2A tolerance, fully threaded design, and precise 1-1/2" length with manufacturing tolerance of -0.03" to 0". The screw meets RoHS 3 (2015/863/EU) compliance standards and REACH (EC 1907/2006) regulations for hazardous substances. Manufactured with thread-forming tapping method and right-hand thread direction, these industrial fasteners are designed for use with 5.5mm (0.2165") drill bits in aluminum, brass, and copper applications.
