Professional Applications & Engineering Value
This stainless steel shoulder screw is engineered to address critical alignment and durability challenges in industrial applications such as machinery assemblies, pivoting mechanisms, and precision instruments. The 18-8 Stainless Steel material, combined with a passivated finish, provides excellent resistance to corrosion and wear, extending service life in moist or chemically aggressive settings. The 10-32 UNF fine thread and Class 2A fit ensure tight, reliable fastening that minimizes loosening under vibration, while the precisely machined 2-1/4" shoulder acts as a stable axle or spacer for rotating parts, reducing misalignment and maintenance needs. Its hex socket drive allows for straightforward installation with standard tools, enhancing assembly efficiency in compact designs.
Specification Summary & Compliance
This shoulder screw adheres to inch system dimensions with a Class 2A thread fit for consistent accuracy. The shoulder features a diameter of 1/4" (tolerance: -0.001" to 0") and length of 2-1/4" (tolerance: 0" to 0.002") for precise assembly. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and compliance in industrial use.
