S-90265A547 M2 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and black oxide finish for extended service life in harsh environments
• Enhanced grip and tool engagement thanks to the knurled socket head and 2mm hex drive, preventing slippage during installation
• High mechanical strength with 70,000 PSI tensile strength and 45,000 PSI shear strength for reliable performance under load
• Precision alignment and spacing enabled by the 4mm shoulder diameter and 8mm shoulder length for accurate component positioning
• Consistent thread quality with Class 5g6g thread fit and coarse M2 x 0.4mm pitch ensuring secure fastening and vibration resistance
• Industry-standard compliance meeting ISO 7379 specifications, RoHS 3, and REACH for global regulatory acceptance
• Durable material properties featuring Rockwell B83 hardness for excellent wear resistance and long-term reliability

Professional Applications & Engineering Value

This M2 shoulder screw delivers exceptional engineering value in precision assemblies where alignment and corrosion resistance are critical. The 18-8 stainless steel base material combined with black oxide finish provides superior protection against oxidation and chemical exposure, making it ideal for electronics, medical devices, and automotive components. The knurled socket head with 2mm hex drive ensures positive tool engagement, reducing installation errors in confined spaces. The precisely machined shoulder (4mm diameter, 8mm length) acts as a pivot or spacer, maintaining accurate component positioning while the Class 5g6g metric thread ensures vibration-resistant fastening. These features collectively solve common industrial challenges of misalignment, corrosion-induced failure, and assembly inefficiency in precision engineering applications.

Specification Summary & Compliance

This metric shoulder screw features M2 x 0.4mm coarse threads with Class 5g6g thread fit tolerance, ensuring precise engagement. Shoulder dimensions maintain tight tolerances (diameter: -0.072 to -0.01 mm; length: 0 to 0.25 mm) for accurate assembly. Manufactured to ISO 7379 standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and international quality acceptance.
