Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional value in applications requiring accurate component positioning and rotational control. The 14mm shoulder length with precise tolerances serves as a reliable locating dowel or pivot point in assemblies, eliminating the need for additional bushings or spacers. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance while maintaining 70,000 psi tensile strength for high-stress environments. The socket head design with hex drive allows for compact installation in confined spaces, while the Class 6g thread fit ensures consistent performance in automated assembly systems. These metric shoulder screws are particularly valuable in precision machinery, optical equipment, and electronic enclosures where dimensional stability and corrosion resistance are critical.
Specification Summary & Compliance
This M2 shoulder screw features metric coarse threads (0.4mm pitch) with Class 6g thread fit per ISO standards. The precision shoulder maintains diameter tolerance of -0.025 to 0mm and length tolerance of 0 to 0.05mm. Manufactured from 18-8 stainless steel with Rockwell B55 hardness, the screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material compliance.
