S-97307A114 M3 DIN 923 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Precise component alignment ensured by the 4mm diameter shoulder with a tight tolerance fit, reducing assembly errors and improving product quality.
• High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance under significant loads and stress.
• Efficient installation and removal facilitated by the low socket head design, allowing for compact spaces and secure tool engagement.
• Consistent thread engagement due to the Class 6g thread fit and coarse M3x0.5 thread pitch, enabling faster assembly and reduced cross-threading risks.
• Compliance with international standards including DIN 923, ensuring dimensional accuracy and interchangeability in global engineering applications.
• Environmental and safety adherence with RoHS 3 and REACH compliance, meeting stringent regulatory requirements for hazardous substance control.

Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for automotive, electronics, and machinery sectors where exposure to moisture or chemicals is common. The 4mm shoulder diameter and precise fit prevent lateral movement, ensuring accurate positioning of components like gears, pulleys, and bearings. With a low socket head and right-hand coarse thread, it allows for easy installation in confined spaces while maintaining high tensile strength. These features reduce maintenance downtime and enhance the reliability of industrial equipment, providing long-term value in demanding applications.

Specification Summary & Compliance

This metric shoulder screw adheres to DIN 923 standards, with a Class 6g thread fit for consistent dimensional accuracy. The shoulder diameter tolerance is -0.03 to 0 mm, and shoulder length tolerance is 0.07 to 0.15 mm, ensuring precise assembly. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe industrial use.
