Professional Applications & Engineering Value
These 8-32 UNC zinc-plated steel screws with T20 Torx drive deliver exceptional performance in industrial fastening applications where reliability and durability are paramount. The zinc-plated steel construction provides superior corrosion protection, extending component life in manufacturing equipment, machinery assemblies, and electronic enclosures. The rounded pan head design offers an optimal balance between low-profile installation and sufficient bearing surface, while the coarse UNC threading ensures rapid assembly and superior resistance to vibrational loosening. Engineered with fully threaded construction, these screws maintain consistent clamping force across the entire 1/4" length, making them ideal for applications requiring secure fastening in limited space configurations.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (8-32 size) in the inch measurement system. These screws conform to ASME B18.3 standards for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. With right-hand thread direction and fully threaded construction, these fasteners ensure reliable performance across industrial applications requiring 40,000 psi tensile strength and Rockwell B70 hardness specifications.
