Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and durability challenges in industrial machinery. The 18-8 stainless steel material provides excellent corrosion resistance, extending service life in humid or chemically exposed environments. The 20mm shoulder with precise fit tolerance acts as a reliable pivot or spacer, eliminating misalignment in rotating assemblies like conveyor systems, printing equipment, and automation guides. Combined with the M10 coarse thread and Class 6g thread fit, it ensures rapid, secure fastening that withstands operational vibrations. The hex socket drive allows for flush mounting and high-torque installation in confined spaces, making it a top choice for OEMs and maintenance teams requiring repeatable precision and long-term reliability.

Specification Summary & Compliance

This shoulder screw features a metric M10x1.5 coarse thread with Class 6g thread fit per ISO standards, ensuring dimensional accuracy. The shoulder diameter is manufactured to a tight tolerance of -0.025 to 0 mm, and the shoulder length to 0 to 0.05 mm, guaranteeing a precise fit for alignment-critical applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial sectors.
