Professional Applications & Engineering Value
These zinc-plated steel screws with T8 Torx drive and black painted finish deliver exceptional performance in demanding industrial environments. The combination of 2-56 UNC coarse threading and Class 2A thread fit ensures rapid installation with minimal cross-threading risk, while the rounded pan head provides both aesthetic appeal and practical clearance advantages. Engineered for applications requiring high torque transmission and corrosion resistance, these fully threaded fasteners maintain structural integrity in electronics, machinery, and automotive assemblies where vibration resistance and consistent clamping force are critical. The Rockwell B70 hardness rating guarantees durability against stripping and deformation during repeated installation cycles.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and 2-56 UNC coarse thread specifications. Complies with ASME B18.6.3 manufacturing standards while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features right-hand threading with fully threaded 1/4" length and standardized pan head profile for consistent performance across industrial applications.
