S-96655A121 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• High mechanical strength and durability from a Rockwell B55 hardness and 70,000 psi tensile strength, ensuring reliable performance under load.
• Precise component alignment and smooth rotation enabled by the 5/16" diameter shoulder with controlled tolerances.
• Secure, non-slip fastening thanks to the knurled socket head and standard hex drive, preventing tool slippage during installation.
• Optimized for quick assembly with coarse UNC threads and a Class 2B thread fit, reducing installation time.
• Versatile partial threading allows the unthreaded shoulder to act as a pivot, bearing, or spacer in assemblies.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, ensuring safety and market acceptability.

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address common assembly challenges in machinery, automation, and precision equipment. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it suitable for demanding environments like food processing or outdoor applications. The 1-1/4" shoulder length and 5/16" shoulder diameter provide a stable axis for rotating parts, reducing wear and ensuring accurate alignment. With a knurled socket head and hex drive, it allows for secure torque application without cam-out, enhancing worker safety and efficiency. The partially threaded design and coarse threads facilitate quick installation and disassembly, saving time in maintenance and production lines. Ideal for use in pivots, linkages, and as a spacer, this screw delivers reliable performance and long-term durability.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2B thread fit for consistent engagement. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", ensuring high dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances and safe for various industrial applications.
