S-96655A119 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• Precise shaft alignment and secure component positioning thanks to the 1" shoulder with tight tolerances (±0.005") and standard shoulder fit.
• High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness, providing dependable performance under load.
• Easy installation and removal using a standard 5/32" hex drive and knurled head for enhanced grip and torque application.
• Reliable coarse threading with 6-32 UNC Class 2B threads, offering excellent engagement and vibration resistance in dynamic applications.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, making it suitable for global markets and sensitive applications.
• Versatile partial threading allowing the 1/4" thread depth to securely fasten components while the unthreaded shoulder acts as a precise pivot or axle.

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 1" shoulder length with minimal tolerances ensures exact component spacing and rotational stability, preventing misalignment in industrial machinery and automation systems. The 6-32 UNC coarse thread and Class 2B thread fit provide robust fastening that resists loosening under vibration, while the partially threaded design allows the shoulder to serve as a bearing surface or dowel. Made from corrosion-resistant stainless steel with a socket head and knurled texture, it enables easy installation in confined spaces, reducing assembly time and improving maintenance efficiency in precision equipment.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2B thread fit for consistent engagement. Dimensional precision is maintained with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in environmentally conscious industries.
