S-90269A759 M8 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure.
• Exceptional 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 12mm shoulder diameter with tight tolerance, reducing component wear and misalignment.
• Secure and efficient installation with a hex socket drive and knurled head, providing excellent grip and preventing tool slippage during torque application.
• Consistent thread engagement due to Class 5g6g thread fit and M8x1.25 coarse thread design, ensuring easy assembly and vibration resistance.
• Long-term operational reliability backed by Rockwell B79 hardness, maintaining dimensional stability under stress and repeated use.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safety and sustainability in regulated industries.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and assembly jigs where alignment and durability are paramount. The 316 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and food-grade equipment. The knurled head design enhances grip during manual adjustments, while the hex socket drive allows for high-torque installation in confined spaces. The 12mm shoulder diameter acts as a precise pivot or spacer, minimizing backlash and wear in rotating assemblies. With a coarse thread (M8x1.25), it ensures quick assembly and robust performance in high-vibration environments, reducing maintenance downtime and improving overall system integrity for industrial applications.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional tolerances, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The thread is manufactured to Class 5g6g fit per ISO metric standards, ensuring consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of restricted hazardous substances for safe use in various industrial sectors.
