S-90318A890 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial and marine environments
• Precise component alignment enabled by the 6mm shoulder diameter with tight tolerance for reduced vibration and wear
• High-strength performance delivering 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
• Space-saving installation with ultra-low socket head design, allowing use in confined spaces with a standard 3mm hex key
• Reliable thread engagement thanks to Class 6g thread fit and M5x0.8 coarse thread for quick assembly and vibration resistance
• Consistent dimensional accuracy with precisely controlled shoulder length and diameter tolerances for repeatable performance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

Engineered for precision motion control and assembly, this M5 shoulder screw solves critical alignment challenges in industrial machinery, robotics, and automotive fixtures. The 316 Stainless Steel material provides exceptional resistance to chemicals, saltwater, and extreme temperatures, while the precise shoulder diameter acts as a built-in locating dowel to eliminate component misalignment. The ultra-low hex socket head minimizes protrusion in compact designs, and the Class 6g thread fit ensures secure fastening in high-vibration environments. Ideal for securing bearings, gears, and linkages where dimensional stability and corrosion resistance are paramount.

Specification Summary & Compliance

This metric shoulder screw features M5x0.8 coarse threads with Class 6g tolerance, a shoulder diameter of 6mm (-0.025 to 0mm tolerance), and shoulder length of 10mm (0 to +0.05mm tolerance).
