Professional Applications & Engineering Value
This 10-32 UNF thread shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining component alignment and resisting loosening under dynamic loads. Made from 316 Stainless Steel, it offers exceptional resistance to corrosion from chemicals, moisture, and saltwater, making it suitable for marine, chemical processing, and food industry equipment. The black oxide finish not only enhances its aesthetic but also reduces friction and wear during installation. With a Class 3A thread fit and fine UNF threading, it provides tight tolerances that prevent backlash in machinery, while the knurled socket head allows for secure tool engagement in confined spaces. Ideal for use in pivots, rotating shafts, and jigs, this screw ensures long-term reliability and reduces maintenance needs in industrial settings.
Specification Summary & Compliance
This shoulder screw features precise dimensional controls, including a Class 3A thread fit for high accuracy, and shoulder diameter and length tolerances as specified. It adheres to ASME B18.3 manufacturing standards, ensuring consistent quality and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various applications without hazardous substances.
