S-96660A177 3/8"-16 x 3/4" Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with zinc-plated alloy steel construction, extending service life in harsh industrial environments
• Superior load-bearing capacity with 120,000 psi tensile strength and Rockwell C32 hardness for reliable performance under heavy stress
• Effortless installation and removal using the 7/32" hex drive, ensuring maximum torque transmission without stripping
• Secure fastening in coarse materials with UNC coarse threads and Class 3A fit, providing excellent grip and vibration resistance
• Enhanced surface distribution from the wide button head and integrated flange, reducing surface damage and improving joint integrity
• Full-thread engagement for consistent clamping force along the entire 3/4" length, minimizing loosening in dynamic applications
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable usage

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these zinc-plated alloy steel rounded head screws deliver critical performance where vibration resistance and structural integrity are paramount. The UNC coarse thread design excels in softer materials and high-vibration environments like machinery assembly, automotive frames, and construction equipment, preventing thread stripping under dynamic loads. With Class 3A thread fit precision and fully threaded construction, they ensure uniform stress distribution and eliminate weak points in joints. The flanged button head provides a wider bearing surface, protecting assembled materials from deformation while the hex drive allows for high-torque installation in confined spaces. Ideal for heavy-duty fastening in manufacturing, metalworking, and structural applications requiring reliable, long-term connections.
