- Versatile right-hand threading compatible with standard UNF components for easy integration into existing assemblies
Professional Applications & Engineering Value
This alloy steel shoulder screw delivers critical engineering solutions where precision alignment and high strength are paramount. The black oxide finish provides essential corrosion protection in manufacturing environments while maintaining dimensional stability. The 5/8" shoulder diameter with precise tolerances eliminates play in rotating assemblies, making it ideal for precision machinery, automotive components, and industrial equipment where misalignment causes premature wear. The Class 3A UNF fine threads maintain clamping force under vibration, while the 140,000 psi tensile strength ensures reliability in high-load applications. The combination of knurled head texture and hex drive facilitates secure installation in confined spaces, reducing assembly time and improving maintenance efficiency.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit for superior engagement and UNF fine thread specifications. Shoulder diameter tolerance maintained at -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" for precision alignment. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards.
