Professional Applications & Engineering Value
These zinc-plated steel tapping screws are specifically engineered for plastic fastening applications where reliable, long-term connections are critical. The thread-forming TRS design with Tri-Lobe shank cross-section displaces plastic material during installation, creating permanent, vibration-resistant threads without chip formation. This eliminates the need for pre-tapped holes while providing superior pull-out resistance compared to standard screws. The T25 Torx drive system ensures maximum torque transmission without stripping, making these No. 10 x 5/8" screws ideal for high-volume assembly operations in automotive trim, electronic enclosures, and industrial plastic components where consistent performance and corrosion resistance are essential.
Specification Summary & Compliance
These thread forming tapping screws feature a No. 10 thread diameter (0.19") with 14 threads per inch and 5/8" length, utilizing right-hand threading with blunt tip and fully threaded design. The pan head configuration with T25 Torx drive provides secure fastening capability. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, these screws are designed for use with No. 15 drill bits (0.18" diameter) in plastic materials, ensuring proper fit and optimal thread formation.
