S-90323A261 M10 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
• Precise alignment and smooth rotation due to the 12mm shoulder diameter with tight tolerance (-0.025 to 0mm), reducing wear in assemblies.
• High load-bearing capacity with 80000 psi tensile strength and Rockwell B95 hardness, providing dependable performance under stress.
• Secure and efficient installation using the 6mm hex socket drive, allowing for high torque application without slippage.
• Accurate and reliable thread engagement with Class 6g metric coarse thread (M10x1.5), ensuring consistent fit in industrial applications.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making it suitable for regulated industries.
• Optimized for repetitive use with a smooth, low-profile socket head and right-hand thread direction, facilitating quick assembly and disassembly.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. Made from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure, ideal for machinery, automotive, and electronics where durability is critical. The precise shoulder fit (12mm diameter with tight tolerance) ensures components rotate or pivot smoothly without loosening, reducing maintenance needs. With a Class 6g thread fit and coarse 1.5mm pitch, it offers quick assembly in high-vibration environments, while the socket head design with hex drive allows for compact installations. This combination of metric specifications and robust materials delivers reliable performance in demanding applications like precision instruments and conveyor systems.

Specification Summary & Compliance
