Professional Applications & Engineering Value
This precision shoulder screw with 8-32 UNC coarse threads and 3/16" shoulder diameter solves critical alignment and vibration challenges in industrial machinery. The 18-8 stainless steel construction provides excellent corrosion resistance while the permanent nylon patch thread locker prevents loosening under extreme vibration conditions from -70° to 250°F. Engineered with Class 2A thread fit and precise shoulder dimensions, this socket head shoulder screw ensures accurate component positioning in precision assemblies, automation equipment, and mechanical linkages where dimensional stability and vibration resistance are paramount. The combination of 70,000 psi tensile strength and Rockwell B55 hardness makes it ideal for high-stress applications requiring durable fastening solutions.
Specification Summary & Compliance
This shoulder screw features 8-32 UNC coarse threads with Class 2A thread fit for precise tolerance control. The shoulder maintains a diameter of 3/16" with tolerance of -0.001" to 0" and length of 3/8" with tolerance of 0" to 0.002" for exacting mechanical requirements. Manufactured from 18-8 stainless steel with permanent nylon patch thread locker, the fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial applications worldwide.
