S-90269A627 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• High mechanical strength offering 70,000 psi tensile strength and 35,000 psi shear strength for reliable performance under load.
• Precise component alignment enabled by the 15mm shoulder with controlled diameter tolerance for smooth bearing or bushing fit.
• Secure and non-slip installation with a knurled socket head and 4 mm hex drive, preventing tool slippage during tightening.
• Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective appearance.
• Accurate and reliable threading with Class 5g6g fit and M5x0.8 coarse pitch for easy assembly and strong fastening.
• Compliance with environmental standards, being RoHS 3 and REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and pivot point requirements in mechanical assemblies. The 316 stainless steel material provides exceptional resistance to chemicals and saltwater corrosion, making it suitable for marine, chemical processing, and food machinery applications. The precision 15mm shoulder length and 8mm shoulder diameter with tight tolerances ensure exact positioning for rotating components like gears, pulleys, and linkages, reducing wear and maintenance. The black oxide finish not only enhances corrosion protection but also minimizes light reflection in sensitive equipment. Combined with the socket head and knurled texture, it allows for high-torque installation in confined spaces, ensuring a secure fit that withstands vibration and dynamic loads in industrial shoulder screw applications.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 coarse thread with a Class 5g6g thread fit per ISO standards, ensuring precise and reliable fastening. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, providing high dimensional accuracy for engineering applications. Manufactured from 316 stainless steel with a Rockwell B79 hardness, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for environmentally conscious and regulated industrial uses.
