S-90265A352 M8 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and reducing replacement frequency.
• High torque transmission and secure fastening enabled by the hex socket drive and 6 mm drive size, minimizing tool slippage.
• Exceptional mechanical strength with 70,000 psi tensile and 45,000 psi shear strength, ensuring reliable performance under heavy loads.
• Precise alignment and smooth rotation due to the knurled head and standard shoulder fit, enhancing assembly accuracy.
• Durable thread engagement with Class 5g6g thread fit and coarse 1.25 mm pitch, providing vibration resistance and easy installation.
• Consistent dimensional stability from tight shoulder tolerances (diameter: -0.072 to -0.01 mm, length: 0 to 0.25 mm), ensuring repeatable fits.
• Compliance with global standards including ISO 7379, RoHS 3, and REACH, guaranteeing safety and regulatory adherence for industrial use.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The 18-8 Stainless Steel material offers excellent corrosion resistance, making it suitable for applications in humid or chemical-exposed environments like automotive assemblies and food processing equipment. The metric coarse thread with a 1.25 mm pitch ensures quick and secure fastening, reducing assembly time while the hex socket drive allows for high-torque applications without stripping. The precise shoulder diameter and length provide stable pivoting and alignment in rotating parts, minimizing friction and extending the lifespan of connected components. Ideal for use in precision instruments, conveyor systems, and robotic arms, this screw enhances operational reliability and reduces maintenance costs.
