Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws deliver critical performance advantages for heavy-duty industrial applications where reliability is paramount. The combination of 140,000 psi tensile strength and Rockwell C39 hardness ensures these fasteners maintain integrity under extreme mechanical stress, while the Class 3A thread fit provides precise engagement that resists loosening from vibration. The low-profile socket head with 1/4" hex drive accommodates space-constrained assemblies without compromising torque transmission. Ideal for machinery, equipment manufacturing, and structural frameworks, these partially threaded screws with coarse UNC threading offer efficient installation and superior clamping performance in demanding engineering environments.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit precision and UNC coarse thread specifications. These socket head cap screws comply with ASTM A574 manufacturing standards and meet critical regulatory requirements including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance. The 3" length with 1-1/4" minimum thread length provides optimal engagement for secure fastening in industrial assemblies.
