S-90269A446 M1.6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extending service life.
• Enhanced durability and wear resistance from the black oxide finish, providing a protective layer against abrasion and galling.
• High mechanical strength offering 70,000 PSI tensile strength and 35,000 PSI shear strength for reliable performance under load.
• Precise thread engagement with Class 5g6g thread fit ensuring consistent, secure fastening in metric assemblies.
• Efficient torque transmission via the 2 mm hex socket drive, reducing the risk of tool slippage and head stripping.
• Stable shoulder alignment with a 5 mm shoulder length and controlled tolerances for accurate component positioning.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable use.

Professional Applications & Engineering Value

This M1.6 shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 316 stainless steel material provides excellent resistance to chemicals and moisture, making it suitable for industrial applications in electronics, medical devices, and automotive systems. The black oxide finish reduces friction and prevents seizing, while the coarse thread with 0.35 mm pitch ensures quick and secure fastening. The hex drive design allows for high torque application without cam-out, enhancing assembly efficiency and reliability in tight spaces.
