Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The UNC coarse threads and Class 3A fit provide excellent engagement and vibration resistance, making it ideal for applications in robotics, automotive systems, and electronic enclosures where alignment and durability are paramount. The black oxide finish not only enhances corrosion resistance but also minimizes galling and seizing in high-temperature or humid environments. With a knurled head and hex socket drive, it allows for efficient installation in confined spaces, reducing assembly time and improving operational reliability in industrial settings.
Specification Summary & Compliance
This shoulder screw features a 2-56 UNC thread with Class 3A fit for high precision, along with shoulder diameter and length tolerances of -0.004" to -0.002" and -0.005" to 0.005", respectively. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring adherence to environmental and safety regulations for industrial components.
