Key Features & Benefits at a Glance

  • Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh chemical and marine environments.
  • Precise component alignment enabled by the 12mm shoulder diameter with tight tolerance, ensuring stable assembly and reduced wear.
  • High-strength performance offering 70,000 psi tensile strength and 35,000 psi shear strength for demanding mechanical applications.
  • Enhanced torque transmission from the knurled socket head and 6mm hex drive, preventing tool slippage during installation.
  • Reliable thread engagement with Class 5g6g metric coarse thread (M10x1.5), providing consistent fit and vibration resistance.
  • Durable industrial lifespan supported by Rockwell B79 hardness, maintaining integrity under repeated stress.
  • Compliance with global standards including RoHS 3 and REACH, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and structural assemblies. The 316 Stainless Steel material delivers exceptional resistance to chemicals, chlorides, and oxidation, making it suitable for food processing, medical equipment, and offshore applications. The 12mm shoulder diameter acts as a precise pivot or spacer, eliminating misalignment and reducing bearing surface wear. Combined with the Class 5g6g thread fit and coarse thread pitch, it ensures secure fastening in high-vibration environments, while the knurled socket head enhances grip for efficient torque application with standard hex tools. This design minimizes assembly time and improves long-term reliability in industrial shoulder screw applications.

Specification Summary & Compliance

The screw features a metric M10x1.5 coarse thread with Class 5g6g tolerance for precise fit, a shoulder diameter of 12 mm (tolerance: -0.072 to -0.01 mm), and shoulder length of 12 mm (tolerance: 0 to 0.25 mm). Manufactured to industry standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements for industrial components.
