Professional Applications & Engineering Value
This shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial settings. The alloy steel material, combined with a black oxide finish, offers exceptional resistance to corrosion and mechanical stress, making it ideal for precision machinery, automotive assemblies, and robotic systems. The Class 3A thread fit and fine thread spacing minimize backlash, ensuring stable connections in high-vibration environments. With a 1/2" shoulder diameter and 3/4" shoulder length, it provides reliable pivoting and spacing functions, reducing wear on components and simplifying maintenance. The knurled head and hex drive facilitate efficient installation, saving time in production lines while maintaining high-strength performance under loads up to 140,000 psi.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with a Class 3A thread fit for precise engagement. Dimensions include a shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005", ensuring consistent accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting use in regulated industrial applications without hazardous substances.
