S-90323A336 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh environments and extended service life.
• Precise alignment and secure component mounting thanks to the accurately machined 12mm shoulder with tight diameter and length tolerances.
• High mechanical strength and reliability with 80,000 psi tensile strength and Rockwell B95 hardness, ensuring durability under load.
• Easy installation in confined spaces using the low-profile hex socket head and a standard 3mm hex key.
• Consistent and reliable threading with Class 6g thread fit and coarse M5x0.8 pitch for quick assembly and vibration resistance.
• Compliance with strict environmental regulations, being RoHS 3 and REACH compliant for safe and sustainable use.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address common challenges in assembly and motion control systems. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments. The 12mm shoulder length with precise tolerances ensures accurate positioning of components like gears, pulleys, and linkages, reducing wear and misalignment. The hex socket low head design allows for compact installations where space is limited, while the Class 6g thread fit and coarse thread pitch facilitate quick, secure fastening that resists loosening under vibration. Ideal for use in machinery, automotive, and electronics, this screw enhances performance and longevity in demanding industrial applications.
