• Exceptional holding power from a 70,000 psi tensile strength and Rockwell B70 hardness, ensuring reliable performance under high stress.
• Precise and secure fastening with a Class 3A UNF fine thread fit, minimizing the risk of loosening in critical applications.
• High-torque installation capability via the 3/8" hex drive, allowing for easy and secure tightening with standard tools.
• Consistent quality and interchangeability guaranteed by compliance with the ASME B18.3 standard.
• Full-length threading for maximum grip and adjustability along the entire 1" length of the screw.
• Environmentally responsible manufacturing with compliance to RoHS 3 and REACH regulations.

Professional Applications & Engineering Value

This Socket Head Cap Screw is engineered to solve critical challenges in industrial assembly and machinery. The 18-8 Stainless Steel material provides excellent resistance to corrosion and oxidation, making it a durable choice for applications exposed to moisture, chemicals, or outdoor elements. The fine UNF threads and Class 3A fit offer a tighter tolerance than standard fits, which is crucial for maintaining joint integrity in high-vibration environments like automotive, aerospace, and heavy machinery. The socket head design with a standard profile allows for compact installations in confined spaces where wrench clearance is limited. Its high tensile strength ensures that it can handle significant dynamic and static loads without failure, providing long-term reliability and reducing maintenance downtime in demanding engineering applications.
