Professional Applications & Engineering Value
These zinc-plated steel Torx T8 tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread-forming CA type design creates strong, durable threads in sheet metal without chips or debris, eliminating the need for separate tapping operations and reducing assembly time. The Tri-Lobe shank cross-section provides superior resistance to loosening under dynamic loads, making these UNC coarse thread screws ideal for automotive, electronics enclosure, and HVAC system assemblies. The combination of Torx T8 drive and fully threaded design ensures consistent clamping force distribution and reliable performance in high-vibration environments.
Specification Summary & Compliance
This No. 2-56 x 1/2" tapping screw features precision UNC coarse thread spacing with standard Class 2A tolerances for consistent fit. Manufactured to thread-forming CA type specifications with Tri-Lobe shank geometry and pan head profile. Compliant with RoHS 3 (2015/863/EU) regulations for restricted substance management. Designed for use with No. 48 drill bits (0.076" diameter) to ensure optimal thread engagement in sheet metal applications.
