Professional Applications & Engineering Value

These 6-32 UNC brass flat head screws deliver exceptional engineering value in demanding applications where corrosion resistance, precision fit, and regulatory compliance are critical. The brass material inherently resists rust and galvanic corrosion, making these slotted flat head screws ideal for electrical enclosures, marine hardware, and plumbing systems exposed to moisture. The partially threaded design and coarse thread spacing provide superior holding power in softer materials like wood and plastic, while the 82° countersink angle ensures a clean, flush finish that prevents snagging in assembly lines. With right-hand threading conforming to ASME B18.6.3, these fasteners solve common issues of thread stripping and misalignment, offering reliable performance in construction, industrial machinery, and OEM equipment manufacturing.

Specification Summary & Compliance

This 3" brass flat head screw maintains precise Class 2A thread fit per UNC standards with a thread diameter of 0.138" and minimum thread length of 1 1/2". Manufacturing and quality adhere strictly to ASME B18.6.3 specifications, ensuring dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of restricted hazardous substances for safe use in global markets.
