Key Features & Benefits at a Glance

  • Exceptional corrosion resistance with 18-8 stainless steel and passivated finish for long-lasting performance in harsh environments
  • Precise component alignment enabled by the accurately machined shoulder with tight diameter and length tolerances
  • High-strength fastening with 80,000 psi tensile strength and Rockwell B95 hardness for reliable load-bearing applications
  • Secure, low-profile installation using the hex socket drive that minimizes protrusion while providing strong torque transmission
  • Consistent thread engagement ensured by Class 6g thread fit and coarse pitch for quick assembly and vibration resistance
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
  • Optimized for industrial machinery with metric M10x1.5 right-hand threads compatible with standard components

Professional Applications & Engineering Value

This precision shoulder screw delivers critical engineering value in applications requiring exact component positioning and rotational control. The 18-8 stainless steel construction with passivated finish provides superior corrosion resistance, extending service life in demanding environments like manufacturing equipment, automation systems, and precision instruments. The precise shoulder dimensions (12mm diameter, 10mm length) with minimal tolerances eliminate play between components, preventing misalignment and reducing wear. Combined with the Class 6g thread fit and hex socket drive, this M10x1.5 shoulder screw ensures reliable performance in assemblies where vibration resistance and repeated adjustments are common, making it ideal for jigs, fixtures, and rotating machinery components.

Specification Summary & Compliance

This precision shoulder screw features M10x1.5 metric coarse threads with Class 6g thread fit per ISO standards. Shoulder diameter maintains -0.025 to 0 mm tolerance with shoulder length tolerance of 0 to 0.05 mm for precise fitment. Manufactured from 18-8 stainless steel with passivated finish, it achieves 80,000 psi tensile strength and Rockwell B95 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
