Professional Applications & Engineering Value
This M4 shoulder screw delivers exceptional engineering value in precision assembly applications where alignment accuracy and rotational stability are critical. The alloy steel construction with zinc plating provides reliable corrosion protection in demanding environments such as machinery, automotive components, and electronic enclosures. The precisely machined 5.5mm shoulder diameter acts as a positive locating feature, eliminating misalignment issues that can cause premature wear in rotating assemblies. With its coarse metric thread and Class 6g thread fit, this fastener ensures secure engagement while resisting vibration-induced loosening. The low-profile socket head design accommodates space-constrained applications without compromising accessibility for installation and maintenance.
Specification Summary & Compliance
This metric 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. The Class 6g thread fit ensures proper engagement according to ISO metric standards. Manufacturing complies with DIN 923 specifications for consistent quality and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring compliance with hazardous substance restrictions.
