Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws deliver critical performance advantages in demanding industrial environments. The combination of 10-24 UNC coarse threads with Class 3A precision fit ensures rapid assembly while maintaining structural integrity under vibration and dynamic loads. The nylon patch thread locking feature provides permanent resistance to loosening, making these fasteners ideal for machinery, automotive assemblies, and equipment subjected to thermal cycling between -70° and 250°F. The socket head design with hex drive allows for high torque application in confined spaces, while the fully threaded construction maximizes clamping force distribution. Engineered for applications where vibration-resistant fastening solutions are essential, these screws prevent costly downtime and maintenance issues.
Specification Summary & Compliance
This socket head cap screw features precise 10-24 UNC coarse threads with Class 3A thread fit tolerance for superior engagement. Manufactured to ASME B18.3 specifications with material compliance to ASTM A574. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries. The black-oxide alloy steel construction provides consistent performance with 170,000 psi tensile strength and Rockwell C37 hardness for demanding applications.
