Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction and black oxide finish, ideal for harsh industrial environments
  • Exceptional mechanical strength offering 70,000 psi tensile and 45,000 psi shear strength for heavy-duty, high-stress applications
  • Precision alignment and smooth rotation ensured by the 25mm shoulder with tight diameter tolerance (-0.072 to -0.01 mm)
  • Secure, non-slip installation via the hex socket drive and knurled head texture, preventing tool slippage
  • Reliable thread engagement with Class 5g6g thread fit and M6x1 coarse pitch for quick assembly and vibration resistance
  • Long-term durability backed by Rockwell B83 hardness, maintaining performance under repetitive loads
  • Global compliance and quality assurance meeting ISO 7379 standards and RoHS 3/REACH environmental regulations

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and wear challenges in precision machinery, automation systems, and rotating assemblies. The 25mm shoulder length with controlled tolerance acts as a precise pivot or spacer, reducing bushing wear and eliminating misalignment in industrial equipment. Manufactured from 18-8 stainless steel with a black oxide finish, it resists corrosion in humid or chemically exposed settings, while the hex socket drive and knurled head ensure secure torque transmission. Ideal for securing gears, linkages, and bearings, this metric shoulder screw enhances assembly longevity and reduces maintenance downtime in demanding B2B applications.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise dimensional control. It is manufactured in accordance with ISO 7379 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
