- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Enhanced wear and galling resistance from the TiCN coating, extending service life in high-friction applications.
- Precise component alignment ensured by the tightly toleranced shoulder diameter and length for reliable assembly.
- High-strength fastening with a tensile strength of 70,000 psi and Rockwell B55 hardness for demanding loads.
- Easy installation and removal using a standard 3/32" hex key drive, compatible with common tools.
- Reliable thread engagement with Class 2A UNC coarse threads, providing secure connections in various materials.
- Compliance with global standards including RoHS 3 and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 6-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 3/4" shoulder length with precise tolerances provides a stable pivot or spacer, preventing misalignment in machinery, rotating assemblies, and precision instruments. Made from 18-8 stainless steel and finished with a TiCN coating, it resists corrosion and reduces friction, making it ideal for high-wear environments like automotive, aerospace, and manufacturing equipment. The coarse UNC thread and Class 2A fit ensure quick, secure fastening, while the socket head design allows for compact installations. This combination delivers long-term reliability, reduced maintenance, and consistent performance in B2B procurement scenarios.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder diameter and length are manufactured to tight tolerances (e.g., shoulder diameter: -0.002" to 0", shoulder length: 0" to +0.003") to ensure precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substances.
