Professional Applications & Engineering Value

This M6 shoulder screw, manufactured from 316 Stainless Steel, is engineered to address critical challenges in precision assembly. The 8mm shoulder diameter provides a precise pivot or bearing surface, eliminating the need for separate spacers and reducing component count in assemblies like rotating machinery, linkages, and electronic enclosures. The coarse thread (M6x1mm) ensures rapid assembly and high resistance to loosening under vibration, which is vital in automotive, aerospace, and industrial equipment. The 4mm hex drive and knurled head offer excellent torque transmission and handling, even in confined spaces. Its corrosion-resistant properties make it suitable for applications exposed to moisture, chemicals, or outdoor conditions, ensuring long-term durability and reducing maintenance frequency.

Specification Summary & Compliance

This shoulder screw features an M6x1mm coarse metric thread with a Class 5g6g thread fit for standard tolerance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with ISO 7379 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
