• High tensile strength of 70,000 psi and Rockwell B55 hardness for reliable performance under heavy loads.
• Precise Class 3A thread fit with UNC coarse threading, providing excellent engagement and vibration resistance.
• Fully threaded shank for maximum grip and uniform stress distribution in assemblies.
• Rounded (button) head profile offers a low-profile, aesthetically pleasing finish while minimizing snagging risks.
• Compliance with ASME B18.3, RoHS 3, and REACH ensures adherence to industry standards and environmental safety.

Professional Applications & Engineering Value

These 18-8 stainless steel rounded head screws are engineered to address common industrial challenges, such as corrosion in humid or chemical-exposed settings. The passivated finish enhances durability, while the UNC coarse thread and Class 3A fit deliver secure fastening in materials like metal and plastic, reducing the risk of loosening under vibration. The hex drive allows for high-torque applications in confined spaces, making them ideal for machinery, electronics, and automotive assemblies where reliability and corrosion resistance are critical. By combining high tensile strength with full threading, these screws ensure long-term performance in demanding B2B environments.
