S-90269A539 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• Enhanced durability and wear resistance from the black oxide finish, providing a protective layer against abrasion.
• High-strength performance with 70,000 psi tensile and 35,000 psi shear strength, ensuring reliable load-bearing in demanding applications.
• Precise alignment and smooth rotation due to the smooth, standard shoulder and Class 5g6g thread fit, minimizing assembly play.
• Secure and efficient installation with a hex socket drive, allowing for high torque application in confined spaces.
• Consistent dimensional accuracy with tight shoulder diameter and length tolerances, guaranteeing repeatable assembly and part interchangeability.
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and pivot point requirements in precision machinery. The 316 stainless steel material offers exceptional resistance to chemicals and saltwater, making it suitable for marine, chemical processing, and food-grade equipment. The 70mm shoulder length provides a stable bearing surface for rotating components like gears and linkages, reducing wear and maintaining precise clearances. Combined with the black oxide finish, it enhances corrosion protection and reduces galling. The hex socket head allows for clean, flush installations in tight spaces, while the Class 5g6g thread fit ensures secure fastening without cross-threading. Ideal for applications in robotics, automotive assemblies, and conveyor systems, this fastener delivers reliable performance under high stress and corrosive conditions.

Specification Summary & Compliance

This precision shoulder screw features an M5x0.8 coarse metric thread with a Class 5g6g thread fit for consistent engagement. 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. Manufactured from 316 stainless steel with a black oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, confirming its suitability for environmentally conscious and regulated industrial applications.
