- Precise Class 2A thread fit ensures smooth installation and reliable engagement with mating components
- High tensile strength (50,000 psi) provides exceptional load-bearing capacity for critical fastening applications
- 82° countersink angle enables flush mounting with standard countersunk holes for clean, professional finishes
- Fully threaded design offers maximum grip length and uniform stress distribution across the entire fastener
- Slotted drive compatibility allows for easy installation with standard screwdrivers and manual tools
- Rockwell B50 hardness maintains thread integrity and prevents deformation during repeated use
Professional Applications & Engineering Value
This 3/8"-16 UNC brass flat head screw delivers exceptional engineering value through its combination of corrosion-resistant brass material and precision Class 2A thread fit. The slotted drive style provides reliable installation in applications where power tools cannot be used, while the 82° countersink angle ensures seamless flush mounting in electrical enclosures, marine hardware, and plumbing systems. The coarse UNC threading offers superior resistance to vibration loosening, making it ideal for machinery, industrial equipment, and outdoor applications where environmental factors challenge fastener integrity. With full threading along the entire 1 1/4" length, this screw distributes clamping forces evenly, preventing stress concentration and ensuring long-term joint reliability in industrial brass fasteners applications.
Specification Summary & Compliance
Manufactured to exact ASME B18.6.3 specifications with precise Class 2A thread fit and UNC coarse threading standards. This flat head slotted screw features a standard 82° countersink angle and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement ensures compatibility with North American industrial standards, while the right-hand thread direction and fully threaded design meet industry requirements for reliable mechanical fastening solutions.
