Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and pivot point requirements in industrial applications. The 3-48 UNC coarse thread and Class 3A fit provide superior holding power and resistance to loosening under vibration, a common failure point in machinery. The precision-ground shoulder acts as a reliable axle or dowel, maintaining exact component spacing and reducing wear on moving parts. Its high tensile and shear strength ensures integrity in assemblies subjected to dynamic loads, while the corrosion-resistant material and RoHS/REACH compliance make it suitable for sensitive environments, from food processing equipment to precision instruments.
Specification Summary & Compliance
This shoulder screw features a 3-48 UNC thread with Class 3A fit for high precision. The shoulder diameter is 1/8" with a tolerance of -0.004" to -0.002", and the shoulder length is 3/8" with a tolerance of -0.005" to 0.005". It is manufactured from 18-8 Stainless Steel with a hardness of Rockwell B55. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
