Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision industrial applications. The 18-8 stainless steel material combined with a black oxide finish provides excellent resistance to corrosion and oxidation, extending service life in moist or chemically aggressive settings. The 1-1/2" shoulder length with minimal tolerances ensures precise component spacing, reducing misalignment in machinery, automotive assemblies, and electronic enclosures. The coarse UNC threads and Class 2A fit enhance grip and vibration resistance, while the hex socket drive and knurled head facilitate quick, secure fastening in confined spaces. Ideal for use in pivots, guides, and rotating mechanisms, this screw delivers reliable performance where accuracy and strength are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Dimensions include a thread length of 3/16", shoulder diameter of 3/16" with tight tolerances (-0.004" to -0.002"), and shoulder length of 1-1/2" (-0.005" to 0.005" tolerance). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
