Professional Applications & Engineering Value

These black-oxide alloy steel socket head cap screws deliver critical performance advantages for industrial applications where reliability is paramount. The combination of 170,000 psi tensile strength and Rockwell C37 hardness ensures these 10-24 UNC threaded fasteners maintain integrity under extreme mechanical stress, making them ideal for heavy machinery, automotive assemblies, and precision equipment. The black-oxide surface treatment provides essential corrosion protection while maintaining dimensional stability. With their coarse thread spacing and Class 3A thread fit, these screws offer superior resistance to vibration loosening and ensure consistent clamping force in high-cycle applications. The partially threaded configuration allows engineers to precisely control engagement depth while the hex drive socket enables high-torque installation in confined spaces.

Specification Summary & Compliance

These socket head cap screws feature 10-24 UNC coarse threads with Class 3A thread fit for precision engagement and are manufactured to ASTM A574 specifications for consistent mechanical properties. The fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry standards for restricted substances. With a 1-5/8" length and partial threading configuration, these screws maintain dimensional accuracy throughout their service life.
