S-90265A207 M4 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• Precise alignment and pivot function enabled by the accurately machined shoulder (6mm diameter, 5mm length), reducing component wear.
• High-strength performance with a tensile strength of 70,000 psi and Rockwell B83 hardness for reliable load-bearing in demanding applications.
• Secure and flush installation using the smooth socket head and 3mm hex drive, preventing tampering and providing a clean finish.
• Consistent and reliable threading with a Class 5g6g thread fit and coarse 0.7mm pitch for quick assembly and vibration resistance.
• Global compliance and quality assurance through ISO 7379 certification, ensuring dimensional accuracy and interchangeability.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting strict international regulatory standards.

Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and rotational challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The precise shoulder diameter and length act as a built-in spacer or pivot, eliminating the need for additional bushings and reducing assembly time and parts count. Combined with the coarse thread pitch and Class 5g6g thread fit, it ensures rapid, secure fastening that maintains integrity under dynamic loads and vibrations. The socket head with a 3mm hex drive allows for high-torque installation in confined spaces, providing a reliable fastening solution for precision equipment and automated systems.

Specification Summary & Compliance

This shoulder screw features a metric M4 x 0.7mm coarse thread with a 10mm thread length and a Class 5g6g thread fit for standard tolerance. The shoulder is manufactured to a diameter of 6mm (tolerance: -0.072 to -0.01 mm) and length of 5mm (tolerance: 0 to 0.25 mm). It conforms to the ISO 7379 standard for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
