Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The 1-1/2" shoulder provides exact component positioning in machinery, automation systems, and precision instruments, eliminating misalignment issues. The passivated finish enhances surface durability while the 6-32 UNC coarse thread ensures secure fastening in high-vibration environments. With its low-profile socket head and hex drive configuration, it enables efficient maintenance in confined spaces. These shoulder screws are particularly valuable in manufacturing equipment, robotic assemblies, and electronic enclosures where dimensional accuracy and material integrity directly impact operational reliability and service life.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and shoulder diameter tolerance of -0.001" to 0". The UNC thread system ensures compatibility with standard industrial components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material transparency. Mechanical properties include Rockwell B55 hardness and 70,000 psi tensile strength, meeting industrial performance requirements for precision shoulder screw applications.
