Professional Applications & Engineering Value

This precision shoulder screw delivers critical engineering value in applications requiring exact component positioning and corrosion resistance. The 316 Stainless Steel material provides exceptional performance in marine, chemical processing, and food equipment applications where moisture and corrosive agents degrade ordinary fasteners. The 35mm shoulder length acts as a precision spacer or pivot point in assemblies, eliminating the need for additional bushings while maintaining exact alignment in machinery, robotics, and optical equipment. The hex socket drive with knurled head texture ensures secure tool engagement in confined spaces, while the Class 5g6g thread fit guarantees consistent mating with tapped holes. This combination of precision dimensions, superior material properties, and compliant manufacturing makes these M2 shoulder screws essential for engineers seeking reliability in demanding industrial environments.
