Key Features & Benefits at a Glance
- Precision alignment and reduced wear with a 4mm shoulder diameter providing accurate component positioning and minimizing friction
- Enhanced durability in demanding environments through alloy steel construction with Rockwell B71 hardness and 58,000 psi tensile strength
- Corrosion resistance for extended service life with zinc plating that protects against rust in industrial settings
- Secure fastening with reliable thread engagement thanks to Class 6g thread fit and M3x0.5mm coarse thread spacing
- Space-saving low-profile design with socket head allowing for compact assemblies where clearance is limited
- Consistent performance across applications with DIN 923 standard compliance ensuring dimensional accuracy and interchangeability
- Environmental regulation compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
This M3 shoulder screw delivers critical engineering value in precision assemblies where component alignment and rotational stability are paramount. The alloy steel construction with zinc plating resists corrosion while maintaining structural integrity under repetitive loads. The 4mm shoulder diameter acts as a precise locating feature, eliminating the need for additional alignment components and reducing assembly time. With its low profile socket head and right-hand thread, this fastener is ideal for confined spaces in machinery, automation equipment, and precision instruments. The 2mm shoulder length provides consistent bearing surface, preventing axial movement and ensuring reliable performance in high-vibration industrial environments where metric shoulder screws are specified for their dimensional accuracy.
Specification Summary & Compliance
This shoulder screw features precise dimensional tolerances including shoulder diameter tolerance of -0.03mm to 0mm and shoulder length tolerance of 0.06mm to 0.1mm. Thread specifications include Class 6g thread fit with M3x0.5mm coarse pitch metric threading. Manufacturing complies with DIN 923 standards for dimensional consistency. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations for environmental safety and restricted substances.
