Professional Applications & Engineering Value
This 4-40 UNC shoulder screw is engineered to address critical alignment and rotational challenges in precision assemblies. The 1-1/4" shoulder length provides stable axial support for rotating components like gears and pulleys, minimizing wear and maintaining positional accuracy. Manufactured from 18-8 stainless steel, it delivers excellent corrosion resistance in moist or chemical-exposed environments. The hex socket drive combined with the knurled head texture ensures secure tool engagement during installation, reducing the risk of cam-out in high-torque applications. With its partially threaded design and Class 2B thread fit, this shoulder screw is ideal for machinery, automation systems, and electronic enclosures where precise component spacing and reliable fastening are essential.
Specification Summary & Compliance
This shoulder screw features 4-40 UNC coarse threads with Class 2B thread fit for standard industrial applications. The shoulder diameter maintains a tight tolerance of -0.004" to -0.002", while the shoulder length tolerance is controlled within -0.005" to 0.005" for precise dimensional consistency. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory adherence for global industrial use.
