Key Features & Benefits at a Glance

  • Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
  • Precise alignment and pivot functions enabled by the accurately machined 10mm shoulder with tight tolerances.
  • High mechanical strength and durability from a 70,000 psi tensile strength and Rockwell B55 hardness.
  • Secure and reliable fastening with a Class 6g thread fit and coarse 1mm pitch for quick assembly.
  • Low-profile, space-saving design with a smooth socket head for applications with limited clearance.
  • Guaranteed dimensional consistency and interchangeability through compliance with the DIN 923 standard.
  • Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and wear issues in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in demanding conditions. The precise shoulder acts as a reliable axle or pivot point, ensuring components like gears, linkages, and bearings are perfectly aligned, which minimizes eccentric wear and reduces maintenance downtime. The low socket head design allows for a flush installation in tight spaces, while the coarse metric thread ensures rapid and secure fastening. Its high tensile strength and hardness make it suitable for assemblies subject to significant shear and dynamic loads, providing long-term engineering value and reliability.

Specification Summary & Compliance

This precision shoulder screw features an M6 x 1mm coarse thread with a Class 6g tolerance for a secure fit. The shoulder diameter is 8 mm with a tolerance of -0.036 to 0 mm, and the shoulder length is 10 mm with a tolerance of +0.07 to +0.15 mm, ensuring high dimensional accuracy. It is manufactured to meet DIN 923 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
