S-97307A119 M4 DIN 923 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and reducing long-term replacement costs.
• Precise component alignment ensured by the 10mm shoulder with tight length tolerance (0.07 to 0.15 mm), minimizing assembly play and vibration.
• Reliable thread engagement with Class 6g fit and M4x0.7mm coarse thread, providing consistent fastening strength and easier installation.
• Enhanced durability under load from a Rockwell B55 hardness and 70,000 psi tensile strength, resisting deformation in demanding applications.
• Secure, low-profile fastening with the smooth, low socket head design, allowing for compact assemblies and reduced snagging risks.
• Strict dimensional control on the 5.5mm shoulder diameter (-0.03 to 0 mm tolerance), ensuring interchangeability and precise fit in machined parts.
• Global compliance and safety with DIN 923 standards, RoHS 3, and REACH, meeting international regulatory requirements for industrial use.

Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment and wear issues in precision assemblies. The 18-8 Stainless Steel material offers excellent corrosion resistance, making it suitable for machinery, automotive, and electronics exposed to moisture or chemicals. The 10mm shoulder length with precise tolerances acts as a pivot or spacer, eliminating the need for additional bushings and reducing part count. Its Class 6g thread fit and coarse thread pitch ensure quick, secure fastening in industrial applications, while the low-profile socket head allows for compact designs. By integrating a right-hand thread and smooth finish, it minimizes assembly time and prevents galling, delivering long-term reliability in high-stress environments.

Specification Summary & Compliance

This precision shoulder screw adheres to DIN 923 specifications, with a Class 6g thread fit and tight shoulder diameter tolerance of -0.03 to 0 mm. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety. Manufacturing includes a metric M4x0.7mm coarse thread and precise shoulder dimensions for consistent performance in regulated industries.
