Professional Applications & Engineering Value
This 6-32 UNC shoulder screw is engineered to address critical assembly challenges in industries such as machinery, electronics, and automotive. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, extending service life in humid or chemically aggressive settings. The low socket head design minimizes protrusion, making it perfect for compact assemblies where clearance is limited. The precise shoulder fit acts as a pivot or spacer, ensuring accurate alignment of components and reducing wear. With a coarse thread and Class 2A fit, it delivers strong grip and vibration resistance, streamlining production while maintaining high performance in industrial shoulder screw applications.
Specification Summary & Compliance
The screw features a Class 2A thread fit per UNC standards, with shoulder diameter tolerance of -0.001" to 0" and length tolerance of 0" to 0.002" for high precision. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial uses.
