Professional Applications & Engineering Value
This alloy steel shoulder screw delivers exceptional engineering value in precision assembly applications where alignment and rotational control are critical. The Class 3A thread fit combined with UNF fine threading provides superior vibration resistance in machinery, automotive, and aerospace components. The black oxide finish offers enhanced corrosion protection while maintaining dimensional stability. The precisely toleranced shoulder diameter and length ensure accurate component positioning in jigs, fixtures, and rotating assemblies. The knurled socket head with 3/8" hex drive facilitates secure tool engagement in confined spaces, reducing installation time while preventing cam-out. This combination of features addresses common industrial challenges including misalignment, thread stripping, and corrosion-induced failure.
Specification Summary & Compliance
This shoulder screw maintains Class 3A thread fit precision with UNF thread standards, featuring a 5/8"-18 thread size and 0.625" thread diameter. The shoulder diameter tolerance ranges from -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" for consistent performance. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead as an alloying element in steel and REACH (EC 1907/2006) compliance for safe industrial use.
