Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
- Superior wear protection from TiCN coating that extends service life in high-friction applications
- Precise component alignment through the accurately machined 3/4" shoulder with tight ±0.003" length tolerance
- Reliable fastening performance with Class 2A thread fit ensuring consistent engagement in UNF fine thread applications
- High strength-to-weight ratio delivering 70,000 psi tensile strength for demanding mechanical assemblies
- Optimized torque transmission via hex socket drive design that prevents stripping during installation
- Environmental compliance meeting RoHS 3 and REACH standards for global manufacturing requirements
Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in industrial machinery, robotics, and precision instruments where component positioning is paramount. The 18-8 stainless steel core provides excellent corrosion resistance while the TiCN coating significantly reduces wear in high-cycle applications. The 10-32 UNF fine thread with Class 2A fit ensures vibration-resistant fastening, and the precisely machined 3/4" shoulder length with tight tolerances guarantees accurate bearing surfaces and pivot points. The combination of 70,000 psi tensile strength and Rockwell B55 hardness makes this socket head shoulder screw ideal for applications requiring both structural integrity and repeated disassembly/reassembly cycles.
Specification Summary & Compliance
This shoulder screw maintains Class 2A thread fit per UNF standards with precise shoulder diameter tolerance of -0.002" to 0" and shoulder length tolerance of 0" to 0.003". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while delivering consistent performance in industrial applications requiring right-hand thread fasteners with hex drive installation.
