• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness, providing reliable load-bearing capacity for demanding applications
• Streamlined installation with low-profile socket head and 1/4" hex drive, allowing for easy access in confined spaces and efficient torque application
• Optimized thread engagement with Class 2A UNC coarse threads and 5/8" thread length, ensuring secure fastening and reduced cross-threading risks
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, making it suitable for global manufacturing and export requirements
• Versatile industrial compatibility with right-hand UNC thread pattern, making it interchangeable with standard components across various machinery

Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and rotational control. The 18-8 stainless steel material combined with passivated finish provides superior corrosion resistance, making it ideal for manufacturing equipment, automation systems, and machinery exposed to moisture or chemicals. The low profile socket head design with hex drive enables efficient installation in space-constrained assemblies while maintaining structural integrity. The precisely machined 1/2" shoulder diameter with tight tolerances ensures accurate alignment of moving parts, reducing wear and preventing misalignment in precision instruments, jigs, and fixtures. These shoulder screws are particularly valuable in stripper bolt applications where they guide and support moving components while withstanding significant shear forces.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit with UNC coarse threading (3/8"-16) and maintains precise dimensional tolerances across all critical surfaces. The shoulder diameter tolerance is controlled to -0.001" to 0" with shoulder length tolerance of 0" to 0.002" for consistent performance. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental regulatory adherence for global industrial applications.
