Key Features & Benefits at a Glance
- Superior corrosion resistance from high-quality brass material, ideal for harsh industrial environments and moisture-prone applications.
- Exceptional tensile strength of 50,000 PSI ensures reliable, long-lasting fastening under high-stress conditions.
- Precise Class 3A thread fit guarantees tight, secure connections with minimal risk of loosening or vibration failure.
- Fully threaded design provides consistent holding power along the entire 1-1/4" length for versatile installation.
- 82° countersink angle and flat head profile allow for flush mounting, reducing snag hazards and improving aesthetics.
- Hex drive (7/32") enables easy, high-torque installation with standard tools, speeding up assembly processes.
- Compliance with ASME B18.3, RoHS, and REACH ensures adherence to strict industry and environmental standards for safe, reliable use.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 3/8"-16 UNC brass flat head screws address common challenges like corrosion, vibration, and assembly efficiency. The brass construction naturally resists rust and galvanic corrosion, making them ideal for marine, electrical, and plumbing applications where moisture exposure is frequent. The coarse UNC thread and Class 3A fit provide excellent grip in softer materials or where quick disassembly is needed, reducing strip-out risks. With a Rockwell B55 hardness and 50,000 PSI tensile strength, they maintain integrity under mechanical stress, while the hex drive and flat head design streamline installation in countersunk holes, saving time in high-volume production lines.
Specification Summary & Compliance
This screw meets precise dimensional standards with a Class 3A thread fit for tight tolerances, UNC coarse threading (3/8"-16), and 82° countersink angle. It conforms to ASME B18.3 specifications for consistency and reliability. Environmental and safety compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances for sustainable industrial use.
