Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws are engineered to solve critical fastening challenges in industrial settings. The combination of 6-32 UNC coarse thread and Class 3A precision fit prevents loosening under vibration while enabling quick assembly in production environments. The hex drive system accommodates high torque requirements without stripping, making them ideal for machinery, automotive components, and heavy equipment where space constraints demand socket head profile accessibility. The 170,000 psi tensile strength ensures structural integrity in load-bearing applications, while the protective black-oxide surface treatment resists corrosion in industrial atmospheres, significantly reducing maintenance frequency and replacement costs.
Specification Summary & Compliance
This socket head cap screw features precise 6-32 UNC coarse thread with Class 3A thread fit tolerance for superior engagement. Manufacturing complies with ASTM A574 specification for alloy steel socket head cap screws. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and regulatory adherence for industrial procurement.
