S-90269A431 M1.6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
• Precise and secure shaft location due to the precisely toleranced shoulder, ensuring accurate alignment in assemblies.
• High-strength performance with a tensile strength of 70,000 psi and a shear strength of 35,000 psi for reliable load-bearing applications.
• Secure, low-profile fastening with a socket head and 2 mm hex drive, providing a clean finish and high torque capability in confined spaces.
• Enhanced grip for manual adjustment thanks to the knurled head texture, facilitating easier handling during installation.
• Consistent and reliable thread engagement ensured by the Class 5g6g thread fit, reducing the risk of cross-threading.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring material safety and global market acceptance.

Professional Applications & Engineering Value

This M1.6 shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The 316 Stainless Steel material offers exceptional resistance to chemicals and corrosion, making it indispensable for medical devices, food processing equipment, and marine applications. The knurled head and hex socket drive combine to provide a secure, tool-driven fastening method that is also easy to handle manually. The precisely controlled shoulder diameter tolerance (-0.072 to -0.01 mm) guarantees a perfect slip or press fit into mating parts, eliminating misalignment and reducing assembly time. This metric shoulder screw delivers reliable performance where dimensional accuracy and material integrity are non-negotiable.

Specification Summary & Compliance

This precision shoulder screw features a Class 5g6g thread fit according to metric thread standards, with a coarse pitch of 0.35 mm for the M1.6 thread size. The shoulder diameter tolerance is held to -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. The screw is manufactured to be fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial components.
