S-90269A835 M12 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments like marine or chemical processing.
• Enhanced durability and wear resistance from the black oxide finish, which also reduces light reflection and provides a sleek appearance.
• Precise alignment and smooth rotation thanks to the 60mm shoulder length with tight tolerances, minimizing assembly play and vibration.
• High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength, ensuring reliable load-bearing in demanding applications.
• Secure and efficient installation using the 8mm hex socket drive, allowing for high torque application without slippage.
• Accurate and consistent threading with Class 5g6g thread fit and coarse M12x1.75 pitch, facilitating quick assembly and reducing cross-threading risks.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety, environmental responsibility, and global acceptance.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure in high-stress assemblies. The 316 stainless steel material offers excellent resistance to corrosive elements, making it suitable for applications in marine equipment, food processing machinery, and outdoor structures. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. With a 60mm shoulder length and precise Class 5g6g thread fit, it ensures accurate positioning in pivots, linkages, and rotating assemblies, minimizing wear and extending service life. The hex socket drive allows for secure tightening in confined spaces, ideal for automation systems, conveyor components, and precision instruments where reliability is critical.
