S-90269A744 M8 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Exceptional mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable, heavy-duty load-bearing
• Precise alignment and smooth rotation ensured by the 70mm shoulder with tight diameter tolerance for reduced wear in assemblies
• Secure, non-slip installation with a knurled hex socket head for enhanced grip and torque application
• Consistent thread engagement due to Class 5g6g thread fit and coarse M8x1.25mm pitch, minimizing cross-threading risks
• Durable, wear-resistant surface from the black oxide finish, providing added protection against abrasion and galling
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision equipment. The 316 stainless steel material provides excellent resistance to corrosion from moisture, chemicals, and saltwater, extending service life in demanding applications. The 70mm shoulder length acts as a precise pivot or spacer, reducing bushing wear and maintaining component alignment under dynamic loads. Combined with a black oxide finish and hex socket drive, it ensures easy installation and reliable performance in high-stress environments, from conveyor systems to robotic arms.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
