• Reliable thread engagement through Class 6g thread fit and M6x1mm coarse thread design for quick assembly
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and vibration resistance. The 25mm shoulder length with precise tolerance control provides accurate alignment for rotating assemblies, machinery guides, and precision instruments. The 18-8 stainless steel construction combined with passivated finish ensures long-term corrosion resistance in demanding environments. The integrated nylon patch thread locker eliminates the need for separate locking components, maintaining secure fastening through thermal cycles and vibration. This metric shoulder screw is particularly valuable in automation equipment, manufacturing fixtures, and assembly lines where precise shoulder fit and reliable locking are critical for operational safety and reduced maintenance intervals.
