Professional Applications & Engineering Value
These 10-24 socket head cap screws deliver exceptional engineering value for industrial assembly applications where vibration resistance and structural integrity are paramount. The Black-Oxide Alloy Steel construction provides superior corrosion protection while maintaining the 170,000 psi tensile strength required for heavy machinery, automotive components, and precision equipment. The UNRC coarse thread design ensures rapid installation and reliable performance in high-vibration environments, while the partially threaded configuration concentrates clamping force precisely where needed. These hex drive screws are engineered to withstand extreme operational stresses in manufacturing, aerospace, and automotive applications where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to exacting ASTM A574 specifications with Class 3A thread fit precision and UNRC coarse thread standards. These 1-3/4" length screws feature a 5/32" hex drive and 7/8" minimum thread length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The Rockwell C37 hardness and 170,000 psi tensile strength guarantee consistent performance in the most demanding industrial applications.
