Professional Applications & Engineering Value

This precision shoulder screw is engineered to address common challenges in industrial assembly, such as misalignment and component wear. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to corrosion and oxidation, extending service life in demanding conditions. The 10-32 UNF fine thread and Class 2A thread fit ensure tight, secure fastening with minimal play, while the precisely machined shoulder (2 3/4" length) acts as a reliable pivot or spacer in assemblies like rotating shafts, linkages, and bearing mounts. Its socket head with hex drive allows for easy installation in tight spaces, making it ideal for applications in automation, automotive, and precision machinery where durability and accuracy are critical.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit standards for consistent engagement and features a precise shoulder with diameter tolerance of -0.001" to 0" and length tolerance of 0" to 0.004". Manufactured from 18-8 stainless steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
