Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The UNC coarse thread and Class 3A fit provide excellent engagement in metals and plastics, reducing the risk of cross-threading and ensuring consistent clamp load in high-vibration applications. The knurled head enhances manual handling in tight spaces, while the hex socket drive allows for high-torque installation without stripping. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food-grade equipment, where durability and shoulder positioning accuracy are paramount for maintaining alignment in rotating assemblies or as pivot points.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise tolerance. Key dimensional specifications include a shoulder diameter of 5/32" with a tolerance of -0.004" to -0.002", and shoulder length of 5/16" with a tolerance of -0.005" to 0.005". The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for regulated industries.
