S-90269A551 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or outdoor industrial environments.
• Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective appearance.
• High-strength fastening with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable load-bearing applications.
• Precise alignment and smooth rotation ensured by the smooth, standard shoulder with controlled diameter and length tolerances.
• Secure and flush installation using the hex socket head, allowing for high torque application in confined spaces.
• Consistent and reliable thread engagement with a coarse Metric M5x0.8 thread and Class 5g6g fit for easy assembly and vibration resistance.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and sustainability in your supply chain.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot point challenges in demanding assemblies. The 316 stainless steel material provides exceptional resistance to chemicals, saltwater, and industrial atmospheres, preventing failure in corrosive environments. The precision-machined shoulder with a diameter of 6 mm and length of 12 mm acts as a reliable bearing surface or pivot, reducing wear on connected components and maintaining exact positioning. The black oxide finish not only enhances corrosion protection but also minimizes galling. Combined with the hex socket drive, it offers a clean, low-profile fastening solution for machinery, automotive fixtures, and precision instruments where space is limited and reliability is non-negotiable.

Specification Summary & Compliance

This shoulder screw conforms to Metric standards with an M5x0.8 coarse thread and a Class 5g6g thread fit for standard industrial use. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured from 316 Stainless Steel with a hardness of Rockwell B79. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
