Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in industrial machinery, automation systems, and precision instruments. The 45mm shoulder length with tight ±0.25mm tolerance provides exact bearing surfaces for rotating components, eliminating misalignment issues that cause premature wear. Manufactured from 18-8 stainless steel, it resists corrosion in demanding environments while maintaining dimensional stability. The hex socket drive with knurled head ensures secure tool engagement during installation, preventing stripping in high-torque applications. The M5 x 0.8mm coarse thread with Class 5g6g fit guarantees reliable engagement in metal assemblies, making it ideal for precision positioning in manufacturing equipment, robotics, and mechanical linkages where exact clearance and alignment are paramount.
Specification Summary & Compliance
This metric shoulder screw features precise dimensional tolerances including shoulder diameter tolerance of -0.04 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. Thread specifications include M5 x 0.8mm coarse pitch with Class 5g6g thread fit according to ISO metric standards. The component is manufactured from 18-8 stainless steel with Rockwell B55 hardness and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for industrial applications.
