Professional Applications & Engineering Value

These 6-32 UNC brass flat head screws deliver critical performance in applications where corrosion resistance and precision threading are paramount. The brass material inherently resists oxidation and galvanic corrosion, making these hex drive screws ideal for electrical enclosures, marine hardware, and plumbing systems. The Class 3A thread fit ensures tight tolerances, reducing the risk of loosening under vibration—a common failure point in industrial machinery. With their 82° countersink angle and flat head design, they provide a seamless finish in countersunk holes while the coarse thread spacing enables quick installation in softer materials and blind holes. Engineered to ASME B18.3 specifications, these screws offer reliable, repeatable performance for OEMs and maintenance teams requiring durable brass fasteners.

Specification Summary & Compliance

This product maintains Class 3A thread fit per UNC standards with coarse thread spacing, ensuring precise engagement. Manufacturing adheres to ASME B18.3 specifications for dimensional accuracy, including head diameter (0.263"), length (3/4"), and drive size (5/64"). Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of restricted hazardous substances, supporting use in regulated industries and international supply chains.
