• High-strength fastening with 70,000 psi tensile strength and Rockwell B55 hardness, providing reliable load-bearing capacity for demanding applications.
• Easy installation and removal using a standard 3/32" hex drive socket head, allowing for secure tool engagement in confined spaces.
• Consistent thread engagement with Class 2A fit and coarse 8-32 UNC right-hand threads, enabling quick assembly and vibration resistance.
• Broad regulatory compliance including RoHS 3 and REACH, making it suitable for global industrial and electronic applications.
• Durable, smooth head texture that minimizes friction and damage during installation, ideal for precision machinery components.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel material, combined with a passivated finish, offers excellent resistance to corrosion and oxidation, extending service life in humid or chemically aggressive environments. The 3/16" shoulder length and precise shoulder diameter provide a stable bearing surface for rotating components like gears, pulleys, and linkages, reducing eccentric wear and ensuring smooth operation. With its UNC coarse thread and Class 2A thread fit, it facilitates rapid assembly while maintaining secure fastening under dynamic loads. The socket head with hex drive allows for high-torque installation in tight spaces, making it a reliable choice for CNC equipment, robotics, and assembly jigs where precision and repeatability are paramount.
