S-97595A168 3/8"-16 x 2 1/2" ASME B18.3 Brass Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ensuring long-term reliability in harsh industrial environments
• Exceptional tensile strength rated at 50,000 psi for secure fastening in demanding applications
• Precision Class 3A thread fit provides consistent engagement and reduces the risk of cross-threading during installation
• Optimized 82° countersink angle creates a flush surface finish while maximizing holding power
• Heavy-duty Rockwell B55 hardness maintains structural integrity under repeated stress and vibration
• Full threading along the 2 1/2" length offers maximum adjustability and grip depth in various material thicknesses
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These brass flat head screws with 3/8"-16 UNC coarse threading are engineered to solve critical fastening challenges in industrial settings where corrosion resistance and reliability are paramount. The combination of brass material properties and Class 3A thread precision ensures consistent performance in marine applications, electrical enclosures, and plumbing systems where moisture and chemical exposure would degrade standard steel fasteners. The 82° countersink angle and hex drive design provide secure installation without protrusion, making them ideal for machinery, automotive assemblies, and structural components requiring flush mounting surfaces. Their fully threaded configuration distributes clamping force evenly, preventing loosening under vibration while the coarse thread pitch enables quick installation in soft materials and blind holes.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 specifications, these screws feature Class 3A thread fit for superior dimensional accuracy and interchangeability. The UNC coarse thread series with 3/8"-16 threading provides optimal engagement in various materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. Mechanical properties include 50,000 psi tensile strength and Rockwell B55 hardness for dependable performance in industrial fastening applications.
