Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide coated 18-8 Stainless Steel, ideal for harsh environments and long-term reliability.
- High tensile strength of 80,000 psi ensures secure, durable fastening under significant mechanical stress.
- Rockwell B80 hardness provides excellent wear resistance and maintains thread integrity during installation and use.
- Fully threaded design maximizes grip and holding power across the entire length for stronger assemblies.
- Standard 82° countersink angle and flat head allows for a flush, clean finish, reducing snagging and improving safety.
- No. 2 Phillips drive offers common tool compatibility and efficient installation with reduced cam-out risk.
- Class 2A thread fit with 6-32 UNC coarse thread ensures easy alignment, quick assembly, and reliable performance in various materials.
Professional Applications & Engineering Value
These Black-Oxide 18-8 Stainless Steel flat head screws are engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress demands. The combination of stainless steel material and black-oxide coating enhances durability in moist or chemically aggressive settings, making them ideal for electronics enclosures, machinery panels, and automotive assemblies. The 6-32 UNC coarse thread and fully threaded design provide excellent pull-out resistance and faster installation in metals and plastics, reducing labor time. With a standard 82° countersink, these screws sit flush to prevent interference and maintain aerodynamic or aesthetic surfaces, ensuring your projects meet both functional and design specifications reliably.
Specification Summary & Compliance
This screw features precise Class 2A thread fit per UNC standards, ensuring consistent engagement and ease of assembly. It complies with ASME B18.6.3 for dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for restricted substances. The right-hand coarse thread and specified dimensions (e.g., 5/16" length, 0.262" head diameter) support reliable use in industrial fastening applications.
