Professional Applications & Engineering Value
This alloy steel shoulder screw delivers critical engineering solutions where precision alignment and high-strength fastening are paramount. The 3/8"-24 UNF Class 3A fine threads provide superior resistance to vibrational loosening in machinery, automation systems, and precision equipment. The black oxide finish creates a protective barrier against corrosion while maintaining dimensional stability. The knurled socket head with hex drive ensures secure tool engagement during installation, preventing slippage in high-torque applications. The precisely machined 1/2" shoulder diameter with tight tolerances enables accurate component positioning in assemblies, making it ideal for pivot points, bearing surfaces, and locating applications across industrial manufacturing sectors.
Specification Summary & Compliance
Manufactured to exacting standards, this shoulder screw features Class 3A thread fit for precision applications with UNF fine thread specifications. The component maintains dimensional accuracy with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005".
