Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial applications such as machinery assemblies, pivoting mechanisms, and precision instruments. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, extending service life in moist or chemically aggressive settings. The 1-3/4" shoulder length with controlled tolerances ensures precise positioning of components, reducing misalignment and wear. Combined with a hex socket drive and knurled head texture, it facilitates secure installation and maintenance, while the Class 2A thread fit and fine thread spacing enhance joint integrity under dynamic loads. This design minimizes downtime and improves operational reliability in automated systems and heavy-duty equipment.
Specification Summary & Compliance
The screw features a 10-32 UNF thread with Class 2A fit and fine spacing for precise engagement, a shoulder diameter of 3/16" with tolerances from -0.004" to -0.002", and shoulder length of 1-3/4" with -0.005" to 0.005" tolerance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for global supply chains.
