• High mechanical strength offering 50,000 psi tensile strength and Rockwell B50 hardness for durable fastening
• Broad industrial compatibility through UNC coarse thread and right-hand threading for common applications
• Enhanced safety and compliance meeting RoHS 3 and REACH environmental regulations
• Full-length threading providing maximum grip and load distribution across the entire 7/8" length

Professional Applications & Engineering Value

These 2-56 UNC brass flat head slotted screws are engineered to address critical needs in precision assemblies where corrosion resistance and flush surface requirements are paramount. The brass material inherently resists oxidation and galvanic corrosion, making these fasteners ideal for electrical enclosures, marine hardware, and plumbing systems. The slotted drive style allows for straightforward installation with standard tools, while the coarse thread spacing and Class 2A thread fit ensure rapid assembly and reliable performance in high-vibration industrial settings. With full threading along the 7/8" length, these screws provide uniform clamping force, preventing loosening and maintaining integrity in mechanical and structural applications.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications, these screws guarantee dimensional accuracy with Class 2A thread fit and UNC thread form. They are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet stringent environmental and safety standards for industrial use.
