S-92480A857 1/2"-13 x 1" ASME B18.6.3 Brass Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance due to brass construction, ensuring long-term reliability in harsh industrial environments
• High tensile strength of 50,000 psi provides exceptional load-bearing capacity for demanding applications
• Rockwell B50 hardness maintains structural integrity under repeated stress and vibration
• Class 2A thread fit with UNC coarse threading enables quick installation and secure fastening in various materials
• Standard 82° countersink angle ensures flush mounting for clean, professional finishes
• Phillips No. 4 drive offers familiar, efficient installation with standard tools
• Full threading along 1" length maximizes grip strength and distribution across the entire fastener

Professional Applications & Engineering Value

Engineered for industrial applications where corrosion resistance and reliable fastening are critical, this brass flat head screw solves common challenges in electrical enclosures, marine hardware, and plumbing systems. The combination of UNC coarse threads and Class 2A fit prevents cross-threading while providing excellent holding power in softer materials. The 82° countersink angle and flat head design create seamless surfaces ideal for applications requiring aerodynamic or aesthetic considerations. With 50,000 psi tensile strength and Rockwell B50 hardness, these Phillips drive screws maintain performance in high-vibration environments where inferior fasteners would fail.
