S-90265A104 M1.6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• High-strength performance offering 70,000 psi tensile strength and 45,000 psi minimum shear strength for reliable load-bearing applications.
• Precise thread engagement with Class 5g6g fit and coarse 0.35mm pitch, ensuring consistent assembly and reduced risk of cross-threading.
• Enhanced grip and anti-slip handling due to the knurled socket head design, facilitating easier installation in tight spaces.
• Accurate alignment and spacing provided by the 8mm shoulder length with tight tolerances, minimizing component misalignment.
• Durable wear resistance from Rockwell B83 hardness, extending service life in high-cycle applications.
• Broad compatibility with standard 2mm hex drive tools, streamlining maintenance and assembly processes.

Professional Applications & Engineering Value

This M1.6 shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and vibrational loosening. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for electronics, medical devices, and automotive components where durability is critical. The Class 5g6g thread and coarse 0.35mm pitch ensure quick, secure fastening in metric systems, while the 8mm shoulder length with minimal tolerances acts as a precise spacer or pivot, reducing wear on connected parts. The knurled socket head and 2mm hex drive allow for efficient torque application, even in confined spaces, enhancing assembly speed and reliability in automated or manual industrial settings.

Specification Summary & Compliance

This shoulder screw adheres to metric dimensions with a thread size of M1.6x0.35mm and Class 5g6g thread fit for precise tolerance control. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible and safe industrial use.
