• Secure and non-slip fastening enabled by the knurled socket head, providing excellent grip during installation and removal.
• Broad compatibility with metric coarse (M6x1mm) threading, conforming to the international ISO 7379 standard for interchangeability.
• Environmental compliance assurance by meeting RoHS 3 and REACH regulations, supporting sustainable and safe manufacturing practices.
• Optimized for automated assembly with its hex drive and standard socket head profile, facilitating efficient high-volume production.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point requirements in demanding 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 integral 6mm shoulder acts as a precise locating dowel or bearing surface, eliminating the need for additional spacers and reducing assembly errors. The coarse pitch metric thread (M6x1mm) ensures quick and secure fastening, while the knurled socket head offers superior torque transmission without cam-out. Its high tensile strength and Rockwell B83 hardness guarantee durability in high-stress, dynamic environments, providing long-term reliability and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw features an M6x1mm coarse thread with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter is manufactured to a tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to +0.25 mm for precise assembly. It is produced in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
