• Precision Class 3A thread fit provides tight tolerances for secure fastening and reduced risk of loosening under vibration.
• Fully threaded design allows for maximum grip and adjustability across the entire length, enhancing assembly flexibility.
• 82° countersink angle and flat head enable flush mounting, minimizing protrusion and improving safety in machinery.
• 1/2" hex drive offers easy installation and high torque application with standard tools, reducing assembly time.
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees adherence to industry standards and environmental regulations for safe use.

Professional Applications & Engineering Value

This 3/4"-10 UNC flat head screw in 316 stainless steel is engineered to address critical challenges in industrial settings, such as corrosion from exposure to moisture, chemicals, or saltwater. The passivated finish enhances its longevity by forming a protective layer, while the coarse thread and Class 3A fit ensure quick, secure fastening in materials like metal or wood, reducing the risk of strip-out. Commonly used in construction, marine equipment, and machinery assembly, its fully threaded design and 82° countersink provide a low-profile, vibration-resistant solution that maintains structural integrity under high stress, making it a reliable choice for heavy-duty applications where precision and durability are paramount.

Specification Summary & Compliance

This screw features precise dimensions including a 2 1/2" length, 3/4"-10 UNC coarse thread with Class 3A tolerance for accurate fit, and a head diameter of 1.438" with standard tolerance. It meets ASME B18.3 specifications for consistency and performance, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
