• High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength, providing exceptional load-bearing capacity for demanding applications
• Consistent thread engagement with Class 5g6g metric coarse thread (M3 x 0.5mm), ensuring reliable fastening and vibration resistance
• Secure tool engagement featuring hex socket drive with 2mm drive size and knurled head texture, preventing cam-out during installation
• Enhanced durability with Rockwell B55 hardness, maintaining structural integrity through repeated use cycles
• Regulatory compliance meeting RoHS 3 and REACH standards, ensuring environmental responsibility and global market acceptance

Professional Applications & Engineering Value

This precision M3 shoulder screw with 18-8 stainless steel construction addresses critical alignment challenges in industrial machinery and precision equipment. The precisely machined 4mm shoulder diameter with tight tolerance control (-0.072 to -0.01 mm) ensures perfect bearing surface contact, eliminating component misalignment that causes premature wear in rotating assemblies. The coarse thread pitch (0.5mm) provides superior vibration resistance in high-speed applications while the hex socket drive with knurled head prevents tool slippage during torque-critical installations. Engineered for precision mechanisms, automation systems, and electronic enclosures, this shoulder screw delivers reliable performance where dimensional accuracy and corrosion resistance are paramount.

Specification Summary & Compliance

Manufactured to precise metric standards with Class 5g6g thread fit tolerance for consistent engagement. Shoulder diameter tolerance maintained at -0.072 to -0.01 mm with shoulder length tolerance of 0 to 0.25 mm. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Right-hand coarse thread configuration (M3 x 0.5mm) with standard socket head profile ensures compatibility with industry-standard installation tools and procedures.
