S-90269A146 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• High mechanical strength and durability with 70,000 PSI tensile strength and Rockwell B79 hardness for reliable performance under load.
• Precise shoulder positioning with a 30mm shoulder length and controlled diameter tolerance for accurate alignment in assemblies.
• Secure and efficient installation using a standard 3mm hex socket drive, reducing the risk of tool slippage and damage.
• Consistent thread engagement with a Class 5g6g thread fit and coarse M5x0.8 thread for quick assembly and vibration resistance.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe use in regulated industries.
• Smooth head texture minimizes friction and potential damage to mating surfaces during installation.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides excellent corrosion resistance, making it suitable for machinery, automotive, and marine environments where moisture and chemicals are present. The precision 30mm shoulder ensures accurate component spacing and rotational stability, reducing wear and misalignment in pivots, linkages, and bearing mounts. The hex socket drive allows for high-torque installation in confined spaces, while the coarse metric thread (M5x0.8) facilitates rapid assembly and maintains hold under dynamic loads. This combination of material strength and dimensional accuracy delivers long-term reliability and reduces maintenance needs in demanding engineering setups.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm for consistent performance. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it is free of restricted substances, supporting use in environmentally conscious and regulated industries.
