Professional Applications & Engineering Value

These M3 shoulder screws deliver critical engineering solutions where precise component alignment and rotational control are paramount. The alloy steel construction with black oxide finish provides exceptional durability against corrosion and wear in demanding environments like automation equipment, precision machinery, and electronic assemblies. The 20mm shoulder length acts as a precise pivot or spacer, eliminating the need for additional components while maintaining exact positioning. The hex socket drive combined with coarse metric threading ensures rapid installation and high clamp force retention, significantly reducing assembly time while preventing loosening under vibration. These precision shoulder screws solve common industrial challenges of misalignment, component wear, and maintenance accessibility.

Specification Summary & Compliance

Manufactured to exacting standards with Class 6g thread fit per metric specifications, ensuring precise thread engagement and interchangeability. The shoulder diameter maintains tight tolerance of -0.072 to -0.01 mm while shoulder length tolerance is controlled within 0 to 0.25 mm for consistent performance. These metric shoulder screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for global industrial applications requiring environmental compliance and material safety.
