S-90269A545 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance in harsh environments due to 316 Stainless Steel construction and protective Black Oxide finish.
• Precise alignment and smooth rotation for components with a consistently smooth 6mm diameter shoulder and minimal diameter tolerance.
• High-strength performance under load with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi.
• Reliable and secure fastening ensured by the Class 5g6g thread fit, providing excellent tolerance control for metric assemblies.
• Easy installation and high torque capability with a standard hex socket (3mm drive) and a smooth, standard socket head profile.
• Durable and long-lasting with a Rockwell B79 hardness, offering excellent wear resistance for repeated use.
• Compliant for global industrial use, meeting RoHS 3 and REACH environmental and safety regulations.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot-point challenges in industrial applications. The 80mm shoulder length provides a precise, unthreaded bearing surface, ideal for guiding moving parts like gears, linkages, and pulleys, reducing wear and ensuring smooth operation. Manufactured from 316 Stainless Steel and finished with a Black Oxide coating, it delivers superior corrosion resistance, making it suitable for demanding environments such as marine, chemical processing, and food machinery. The Class 5g6g thread fit guarantees consistent engagement and reliability in metric assemblies, while the hex socket drive allows for efficient installation in confined spaces, maximizing assembly speed and maintenance workflows.

Specification Summary & Compliance

This precision shoulder screw adheres to Metric standards with an M5x0.8 coarse thread and a Class 5g6g thread fit for precise tolerance. The shoulder diameter is 6 mm with a tight tolerance of -0.072 to -0.01 mm, and the shoulder length is 80 mm with a tolerance of 0 to 0.25 mm. The manufacturing and material specifications ensure compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
