S-90269A610 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh or chemically aggressive environments.
• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing in demanding applications.
• Precise alignment and spacing enabled by the 10mm shoulder length with a smooth finish, reducing wear on mating components.
• Secure and flush installation with a hex socket head, allowing for high torque application and a clean, low-profile finish.
• Optimized thread engagement with a Class 5g6g thread fit and coarse M5x0.8 pitch for faster assembly and robust fastening.
• Enhanced durability and wear resistance from the black oxide finish and a Rockwell B79 hardness rating.
• Compliance with global environmental standards, including RoHS 3 and REACH, ensuring suitability for regulated industries.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical challenges in precision assembly and machinery. The 316 stainless steel material provides superior resistance to corrosion, making it an ideal choice for applications in marine, chemical processing, and food-grade equipment where exposure to moisture and corrosive agents is a concern. The integrated 10mm shoulder acts as a precise locating dowel or pivot point, ensuring accurate alignment of parts like gears, bearings, and linkages, which minimizes misalignment and reduces eccentric wear. The black oxide finish not only adds an extra layer of corrosion protection but also reduces galling and friction during installation. Combined with the hex socket drive, it allows for high-torque tightening in confined spaces, providing a secure and reliable fastening solution that maintains integrity under dynamic loads and vibrations.

Specification Summary & Compliance
