Key Features & Benefits at a Glance

  • Enhanced corrosion resistance with 18-8 stainless steel construction and black oxide finish, ideal for harsh industrial environments.
  • Superior load-bearing capacity thanks to 70,000 psi tensile strength and 45,000 psi minimum shear strength for demanding applications.
  • Precise alignment and spacing ensured by the 25mm shoulder with tight diameter tolerance, reducing component wear.
  • Secure, non-slip fastening from the knurled socket head and 6mm hex drive, allowing for high-torque installation.
  • Reliable thread engagement with Class 5g6g thread fit and M10x1.5 coarse pitch for quick assembly and vibration resistance.
  • Long-term durability backed by Rockwell B83 hardness, maintaining performance under repeated stress.
  • Global compliance and safety meeting ISO 7379, RoHS 3, and REACH standards for worry-free international sourcing.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address common industrial challenges like misalignment and component slippage in machinery. The 25mm shoulder length provides a precise unthreaded bearing surface, ideal for pivots, guides, or spacers in automotive, robotics, and assembly equipment. Made from 18-8 stainless steel with a black oxide finish, it offers excellent corrosion resistance, while the knurled socket head and hex drive ensure secure handling during high-torque applications. The Class 5g6g thread fit and coarse pitch enable rapid, reliable fastening, reducing assembly time and minimizing maintenance in high-vibration settings, making it a cost-effective solution for precision engineering needs.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit with an M10x1.5 coarse thread and precise shoulder dimensions (12mm diameter with -0.072 to -0.01 mm tolerance, 25mm length with 0 to 0.25 mm tolerance). 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 international standards adherence.
