S-90323A615 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel and passivated finish for long-lasting performance in harsh environments.
• Precise alignment and pivot function due to the 25mm shoulder with a tight diameter tolerance for reduced assembly play and improved component stability.
• High mechanical strength and durability from Rockwell B90 hardness and 85,000 psi tensile strength, ensuring reliable performance under load.
• Secure and low-profile fastening with the low socket head and 1.5mm hex drive, ideal for applications with limited space.
• Easy and quick installation facilitated by the coarse M2x0.4 thread and right-hand direction, reducing assembly time.
• Consistent thread quality and fit guaranteed by the Class 6g thread fit, promoting reliable engagement and vibration resistance.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, making it suitable for global markets and sensitive applications.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and wear issues in industrial assemblies. The 18-8 stainless steel construction, combined with a passivated finish, provides superior resistance to corrosion and oxidation, extending service life in demanding conditions. The 25mm shoulder length with precise diameter control acts as a reliable pivot or spacer, minimizing misalignment and reducing stress on threaded sections. Its low socket head and hex drive allow for compact designs and secure torque application, making it ideal for machinery, electronics, and automotive components where space and reliability are paramount. The coarse metric thread ensures robust engagement, while high tensile strength supports dynamic loads, delivering consistent performance and reducing maintenance needs.

Specification Summary & Compliance

This M2 shoulder screw features a Class 6g thread fit per metric standards, ensuring dimensional accuracy and compatibility. The shoulder diameter is tightly controlled at 3mm with a tolerance of -0.025 to 0 mm, and the shoulder length is 25mm with a tolerance of 0 to 0.05 mm for precise assembly. Manufactured from 18-8 stainless steel with a passivated surface, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, adhering to environmental and safety regulations for industrial use.
