S-97307A120 M5 DIN 923 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and reducing maintenance frequency.
• Superior strength and durability from a 70,000 PSI tensile strength and Rockwell B55 hardness, ensuring reliable performance under high-stress conditions.
• Precise component alignment enabled by the accurately machined 7mm shoulder diameter with tight tolerances, minimizing assembly play and vibration.
• Optimized for efficient assembly with a low socket head and slotted drive, providing a low-profile design and versatile installation options.
• Reliable thread engagement due to the Class 6g thread fit and M5x0.8 coarse pitch, ensuring secure fastening and resistance to loosening.
• Guaranteed dimensional consistency through compliance with DIN 923 standards, offering interchangeability and predictable performance.
• Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and health safety standards.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The precise shoulder diameter and length with minimal tolerances ensure components like gears, pulleys, and linkages are held securely with exact positioning, reducing wear and misalignment. The low socket head design allows for compact installations where space is limited, while the right-hand metric thread with a coarse pitch facilitates quick and robust fastening. By integrating these features, this screw enhances assembly accuracy, extends equipment lifespan, and minimizes downtime in precision engineering tasks.

Specification Summary & Compliance

This shoulder screw adheres to DIN 923 specifications, ensuring standardized dimensions and performance. The thread fit is Class 6g per metric standards, providing consistent engagement. Critical tolerances include a shoulder diameter of 7 mm with a tolerance of -0.036 to 0 mm and a shoulder length of 6 mm with a tolerance of 0.07 to 0.15 mm for precise fits. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances and suitable for global industrial use.
