• Enhanced load distribution through the integrated flange, minimizing surface damage and improving joint integrity.
• Full thread engagement along the 1" length for maximum grip and stability in a wide range of material thicknesses.
• Compliance with environmental and safety standards, including RoHS 3 and REACH, ensuring suitability for regulated industries.

Professional Applications & Engineering Value

This Black-Oxide Alloy Steel Socket Head Cap Screw is engineered to address critical challenges in heavy-duty and high-stress environments. The combination of alloy steel material and black-oxide surface treatment delivers excellent resistance to corrosion and wear, making it ideal for machinery, automotive, and construction applications where exposure to moisture and chemicals is common. The UNC coarse thread and Class 3A thread fit provide superior holding power and reduce cross-threading risks during assembly, while the flanged design distributes clamping force evenly, preventing damage to connected surfaces. With a 140,000 psi tensile strength and Rockwell C39 hardness, it ensures long-term reliability in dynamic loads and vibration-prone setups, supporting efficient maintenance and reduced downtime.
