• Secure and flush installation using the hex socket drive, allowing high torque application in confined spaces.
• Consistent thread engagement with Class 5g6g fit and coarse 0.7mm pitch, ensuring quick assembly and vibration resistance.
• Durable performance backed by Rockwell B83 hardness, maintaining integrity under repeated stress.
• Global compliance assurance meeting ISO 7379, RoHS 3, and REACH standards for safe, reliable use in regulated industries.

Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and shear stress. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for applications in automotive, electronics, and food processing equipment where moisture or chemicals are present. The hex socket head allows for high-torque tightening without protruding, ideal for compact designs. The 6mm shoulder diameter provides a precise bearing surface, reducing wear on moving parts and ensuring accurate rotational alignment in assemblies like gears, pulleys, and linkages. With its coarse thread pitch and 10mm thread length, it enables rapid installation and secure fastening in high-vibration environments, enhancing overall equipment reliability and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw features a metric M4 x 0.7mm coarse thread with Class 5g6g thread fit for precise tolerance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring accurate fit in assemblies. It complies with ISO 7379 manufacturing standards and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for global industrial use.
