Professional Applications & Engineering Value

This 3/4"-10 UNC shoulder screw is engineered to address critical challenges in machinery assembly, pivoting mechanisms, and precision alignment systems. The 18-8 stainless steel material provides exceptional resistance to rust and chemical exposure, making it suitable for automotive, aerospace, and food processing equipment. The hex socket head design allows for tight spaces installation, while the shoulder diameter acts as a precise pivot or spacer, reducing wear on moving parts. With a coarse thread and Class 2A fit, it ensures rapid, secure fastening in high-vibration environments, minimizing downtime and maintenance costs for B2B clients.

Specification Summary & Compliance

This shoulder screw features a Class 2A thread fit with UNC coarse threads, ensuring dimensional accuracy per inch system standards. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for precise engineering applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety requirements in industrial fastener supply.
