- Superior strength and durability 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 thread fit, minimizing the risk of loosening in critical assemblies.
- Optimized for high-torque applications featuring a hex socket drive (3/32") and standard socket head profile for easy installation and removal.
- Versatile coarse (UNC) threading provides faster assembly and improved performance in materials like aluminum and cast iron.
- Compliance with major industry standards including ASME B18.3, RoHS 3, and REACH, ensuring quality and environmental safety.
- Partially threaded design allows for precise clamping force on specific sections of an assembly.
Professional Applications & Engineering Value
These 5-40 UNC Socket Head Cap Screws are engineered to solve common industrial challenges, such as vibration-induced loosening and material fatigue. The 18-8 Stainless Steel material offers excellent resistance to oxidation and chemical exposure, making these heavy-duty fasteners suitable for machinery, automotive, and marine applications where corrosion resistance is critical. The coarse thread (UNC) and Class 3A thread fit ensure a tight, reliable connection that withstands dynamic loads, while the hex drive design allows for high torque application without slippage. This combination of high tensile strength and precise engineering makes them ideal for securing components in demanding environments, enhancing assembly longevity and reducing downtime.
Specification Summary & Compliance
This product adheres to Class 3A thread fit for high precision, with a UNC coarse thread standard and a minimum thread length of 3/4". Manufacturing and quality are governed by ASME B18.3 specifications. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free from hazardous substances and safe for various industrial uses.
