S-90269A288 M8 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure.
• Precise component alignment and spacing ensured by the 22mm shoulder with controlled diameter and length tolerances.
• High mechanical strength and durability from a Rockwell B79 hardness and 70,000 psi tensile strength for demanding applications.
• Secure and non-slip fastening provided by the knurled head and 5mm hex socket drive for reliable torque transmission.
• Consistent and reliable thread engagement guaranteed by the Class 5g6g thread fit and M8x1.25mm coarse pitch for quick assembly.
• Global compliance and safety with adherence to ISO 7379 standards and RoHS 3 & REACH environmental regulations.
• Excellent shear resistance with a minimum shear strength of 35,000 psi for enhanced joint integrity under lateral loads.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery. The 316 stainless steel material offers exceptional resistance to corrosion and oxidation, making it suitable for applications in marine, chemical processing, and food-grade equipment where moisture and aggressive substances are present. The precision-machined 22mm shoulder acts as a pivot, bearing surface, or spacer, ensuring accurate component positioning and reducing wear on moving parts. The knurled head and hex drive facilitate secure installation and removal, even in high-vibration environments, while the Class 5g6g thread fit provides consistent engagement for reliable fastening. Ideal for use in precision assemblies, robotics, and conveyor systems, this screw enhances equipment longevity and reduces maintenance downtime.
