S-90265A150 M2 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Precise component alignment thanks to the 4mm shoulder diameter with tight tolerance, reducing assembly errors and improving fit.
• High-strength performance offering 70,000 psi tensile strength and 45,000 psi shear strength for demanding industrial applications.
• Easy installation and removal with a hex socket drive and knurled head texture, providing secure grip and reducing tool slippage.
• Reliable thread engagement with Class 5g6g thread fit and coarse M2x0.4 thread pitch, ensuring consistent fastening in various materials.
• Durable and wear-resistant due to Rockwell B83 hardness, maintaining integrity under repeated use and stress.
• Global compliance assurance meeting ISO 7379 standards and environmental regulations like RoHS 3 and REACH for safe, sustainable use.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address common industrial challenges, such as misalignment and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it suitable for precision machinery, electronic enclosures, and automotive assemblies where exposure to moisture or contaminants is a concern. The 4mm shoulder diameter acts as a precise pivot or spacer, ensuring accurate positioning of components like gears or bearings, while the hex socket drive and knurled head enhance torque application and prevent stripping. By integrating a coarse thread and robust tensile strength, this fastener reduces the risk of loosening under vibration, offering long-term stability in heavy-duty applications and streamlining maintenance cycles.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit ensuring dimensional accuracy for metric assemblies. Key tolerances include a shoulder diameter of -0.072 to -0.01 mm and shoulder length of 0 to 0.25 mm, supporting precise engineering requirements. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and alignment with global environmental standards for safe industrial use.
