Professional Applications & Engineering Value
These 2-56 UNC brass flat head screws deliver exceptional value in precision assembly applications where corrosion resistance and reliable fastening are critical. The combination of brass material and Class 2A thread fit ensures consistent performance in electrical components, instrumentation, and marine equipment where exposure to moisture or chemicals would compromise standard steel fasteners. The undercut flat head profile provides superior seating in countersunk holes, preventing protrusion in flush-mount applications while the coarse thread spacing enables quick installation in soft materials or thin sections. These fully threaded screws maintain their 50,000 psi tensile strength across various industrial environments, making them ideal for applications requiring both mechanical reliability and regulatory compliance.
Specification Summary & Compliance
This flat head slotted screw features precise Class 2A thread fit per UNC standards with right-hand threading and coarse thread spacing. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and performance. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and safety in industrial applications.
