Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address critical alignment and strength requirements in precision assemblies. The alloy steel material, combined with a black oxide finish, provides excellent resistance to corrosion and mechanical stress, making it ideal for applications in automotive, robotics, and industrial machinery where repetitive motion and high loads are common. The integrated shoulder with precise diameter and length tolerances acts as a dependable pivot or spacer, reducing component misalignment and wear. Its coarse thread and Class 5g6g thread fit facilitate rapid installation while maintaining secure fastening, minimizing downtime in production lines. By meeting ISO 7379 specifications, this screw ensures interoperability and reliability, supporting efficient B2B procurement for technical projects.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 standards, with a Class 5g6g thread fit for precise metric threading (M4 x 0.7mm coarse). Key dimensional tolerances include a shoulder diameter of 5 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 8 mm (tolerance: 0 to 0.25 mm). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
