Key Features & Benefits at a Glance
- Superior corrosion resistance from 360 Brass material, ideal for harsh environments and reducing maintenance costs
- Precise component alignment ensured by the smooth 3/16" shoulder with tight diameter and length tolerances
- High mechanical strength with 40,000 psi tensile and 22,000 psi shear strength for reliable load-bearing applications
- Easy installation and removal using the 3/32" hex socket drive, minimizing tool slippage and assembly time
- Consistent thread engagement provided by Class 2A UNC coarse threads, reducing cross-threading risks
- Durable performance backed by Rockwell B55 hardness, resisting wear in high-cycle operations
- Global compliance assurance meeting RoHS 3 and REACH regulations for unrestricted industrial use
Professional Applications & Engineering Value
This 360 Brass shoulder screw delivers critical precision in alignment-sensitive assemblies, where its 3/16" shoulder length and smooth head texture prevent component misalignment and reduce wear on mating parts. The 8-32 UNC coarse thread with Class 2A fit ensures rapid, secure fastening in plastics and soft metals, while the hex socket drive allows high-torque installation in confined spaces. Its brass construction naturally resists galvanic corrosion and is non-magnetic, making it ideal for electronics, instrumentation, and marine environments. Engineers rely on its 40,000 psi tensile strength to maintain structural integrity in pivots, linkages, and rotating mechanisms, streamlining production and enhancing product lifespan.
Specification Summary & Compliance
This shoulder screw maintains Class 2A thread fit per UNC standards, with shoulder diameter tolerance of -0.002" to 0" and length tolerance of 0" to 0.003" for precise assembly. Manufacturing adheres to industry standards for inch-system fasteners, with full compliance to RoHS 3 (2015/863/EU) under exemption 6(c) and REACH (EC 1907/2006) regulations, ensuring environmental and safety requirements are met for global industrial applications.
