Professional Applications & Engineering Value
Engineered for demanding industrial applications, these black-oxide alloy steel socket head cap screws deliver exceptional performance where corrosion resistance and high tensile strength are critical. The 10-24 UNC coarse thread configuration provides superior engagement in softer materials and faster installation times, while the Class 3A thread fit ensures precise tolerances for vibration-prone machinery. The combination of 170,000 psi tensile strength and Rockwell C37 hardness makes these fasteners ideal for heavy-duty equipment, automotive assemblies, and precision manufacturing applications where fastener failure is not an option. The black-oxide surface treatment creates a protective barrier against oxidation without compromising dimensional accuracy, offering reliable performance in challenging environments.
Specification Summary & Compliance
Manufactured to exacting ASTM A574 specifications with Class 3A thread fit tolerances for precision applications. Features 10-24 UNC coarse threads with right-hand orientation and standard socket head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global markets.
