Key Features & Benefits at a Glance
- Superior corrosion resistance with 360 Brass construction, ideal for harsh environments and electrical applications
- Precise component alignment enabled by the 1-1/2" shoulder with tight diameter tolerance for reduced assembly vibration
- High mechanical strength delivering 40,000 psi tensile and 22,000 psi shear resistance for demanding industrial applications
- Optimized thread engagement with Class 2A UNC coarse threads ensuring reliable fastening in soft materials
- Secure hex drive installation using standard 3/32" tools preventing cam-out and maintaining head integrity
- Consistent performance backed by Rockwell B55 hardness for maintained dimensional stability under load
- Global compliance assurance meeting RoHS 3 and REACH regulations for international supply chain integration
Professional Applications & Engineering Value
This 360 Brass shoulder screw solves critical alignment challenges in precision assemblies where electrical conductivity and corrosion resistance are paramount. The 1-1/2" shoulder length provides exact positioning for rotating components in machinery, while the UNC coarse threads with Class 2A fit ensure rapid installation in brass and softer materials without stripping. Engineers specify this socket head shoulder screw for jigs, fixtures, and electrical assemblies where the Rockwell B55 hardness maintains shoulder diameter integrity through repeated cycles. The hex drive design allows high torque application in confined spaces, making it ideal for automated manufacturing equipment and precision instrument manufacturing where dimensional stability is critical.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2A thread fit per UNC specifications and precise shoulder diameter tolerance of -0.002" to 0". The 1-1/2" shoulder length maintains 0" to 0.003" tolerance for consistent assembly performance. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial applications.
