S-90269A457 M1.6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction and black oxide finish, ideal for harsh industrial environments.
• Precise alignment and reduced wear thanks to the 3mm shoulder diameter with tight tolerances (-0.072 to -0.01mm) and 10mm shoulder length.
• High mechanical strength delivering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable performance under load.
• Secure and efficient installation with a knurled hex socket head and 2mm drive, preventing cam-out and enabling high torque application.
• Optimized for quick assembly using a coarse pitch (0.35mm) right-hand metric thread with Class 5g6g fit for consistent engagement.
• Durable and long-lasting with Rockwell B79 hardness, ensuring the screw maintains integrity through repeated use.
• Compliant with global regulations including RoHS 3 and REACH, making it suitable for international industrial supply chains.

Professional Applications & Engineering Value

This M1.6 shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and component wear. The 316 stainless steel material combined with a black oxide finish provides excellent resistance to corrosion and oxidation, which is critical in moist or chemically aggressive settings like marine equipment, medical devices, and food processing machinery. The knurled hex socket head ensures a firm grip during installation, reducing the risk of tool slippage and damage. With its 3mm shoulder diameter and 10mm shoulder length, it acts as a precise pivot or spacer, maintaining accurate positioning in rotating parts, jigs, and electronic enclosures. The coarse pitch metric thread and Class 5g6g thread fit facilitate quick and secure fastening, minimizing assembly time while upholding high tensile and shear strength for demanding industrial applications.
