Professional Applications & Engineering Value
This Grade 2 Titanium shoulder screw is engineered to address critical challenges in precision assemblies, such as in aerospace, medical devices, and high-performance machinery. The UNC coarse thread and Class 3A fit provide excellent engagement in materials prone to stripping, reducing the risk of loosening under dynamic loads. The 3/16" shoulder diameter acts as a precise pivot or spacer, minimizing misalignment in rotating parts like bearings or linkages. Made from titanium, it resists corrosion from chemicals and moisture, making it suitable for sterile or outdoor environments. The socket head with knurled texture ensures secure tool grip, speeding up installation in confined areas while maintaining a clean, professional finish.
Specification Summary & Compliance
This shoulder screw features a 3/16" shoulder diameter with a tolerance of -0.004" to -0.002" and a shoulder length of 1/4" with tolerance from -0.005" to 0.005", ensuring precise dimensional control. Threads are 8-32 UNC coarse with a Class 3A fit for high accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
