S-90269A869 M12 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or chemical-exposed environments.
• Enhanced durability and wear resistance from Rockwell B79 hardness, ensuring long service life under mechanical stress.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi shear) for reliable performance in demanding load-bearing applications.
• Precise alignment and spacing provided by the 16mm shoulder diameter and 50mm shoulder length with tight tolerances.
• Secure, non-slip installation with a knurled socket head and 8mm hex drive, allowing for high torque application.
• Consistent thread engagement thanks to Class 5g6g thread fit and coarse M12x1.75mm pitch for quick assembly.
• Regulatory compliance and safety with ISO 7379 standards, RoHS, and REACH, ensuring environmental and health safety in industrial use.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in marine, chemical processing, and food machinery where moisture and chemicals are present. The black oxide finish adds an extra layer of protection against rust while reducing light reflection. With a 50mm shoulder length and precise 16mm shoulder diameter, it ensures accurate component spacing and reduces wear on moving parts, such as in pivots, gears, and rotating assemblies. The coarse thread pitch and hex drive design facilitate quick installation and high clamping force, minimizing assembly time and improving operational efficiency in automated systems and heavy-duty equipment.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit for precise metric threading, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It complies with ISO 7379 manufacturing standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and safe industrial use.
