S-90323A513 M10 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
• Precise component alignment due to the 45mm shoulder with tight tolerances, reducing assembly errors and improving mechanical performance.
• High tensile strength of 80,000 psi and Rockwell B95 hardness for reliable load-bearing in demanding applications.
• Secure, low-profile installation with a hex socket head and 6mm drive, allowing for compact designs and reduced protrusion.
• Consistent thread engagement with Class 6g metric coarse threads (M10x1.5), ensuring easy assembly and vibration resistance.
• Compliance with environmental regulations including RoHS 3 and REACH, making it suitable for global industrial supply chains.
• Smooth, precise shoulder fit with controlled diameter and length tolerances, enabling accurate positioning in machined parts.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation, and precision equipment. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to corrosion and wear, extending service life in moist or chemically aggressive settings. The 45mm shoulder length with precise tolerances acts as a reliable pivot or spacer, minimizing misalignment in assemblies such as rotating shafts, linkages, and bearing mounts. Its hex socket head with low profile allows for compact installations where space is constrained, while the Class 6g thread ensures secure fastening under dynamic loads. Ideal for use in robotics, conveyor systems, and medical devices, this screw delivers consistent performance where precision shoulder screws are essential for operational accuracy and reduced maintenance.
