Professional Applications & Engineering Value
This precision shoulder screw addresses critical alignment challenges in machinery, automation systems, and precision instruments where component positioning is paramount. The 18-8 Stainless Steel material combined with passivated finish provides excellent resistance to corrosion and chemical exposure in demanding industrial environments. The low profile socket head design allows for compact assemblies while maintaining accessibility for standard hex tools. With its 10-32 UNF fine thread and Class 2A thread fit, this fastener ensures vibration-resistant connections in applications requiring precise axial positioning, such as rotating assemblies, pivot points, and bearing retention systems where the 1/4" shoulder diameter serves as a reliable locating feature.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit with UNF thread standard, ensuring precise thread engagement. The shoulder maintains tight dimensional tolerances (-0.001" to 0" diameter, 0" to 0.002" length) for accurate component alignment. Manufactured from 18-8 Stainless Steel with passivated finish, it delivers 70,000 psi tensile strength and Rockwell B55 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
