Professional Applications & Engineering Value
This M4 shoulder screw delivers critical precision alignment in mechanical assemblies where component positioning accuracy is paramount. The 5.5mm shoulder diameter with 2.5mm shoulder length provides exact locating surfaces for gears, bearings, and rotating components, eliminating the need for additional alignment fixtures. Manufactured from heavy-duty alloy steel with zinc plating, it withstands operational stresses while resisting corrosion in industrial environments. The low socket head profile enables flush mounting where clearance is limited, while the Class 6g thread fit and coarse 0.7mm pitch ensure reliable installation in production lines. Ideal for machinery, automotive, and precision equipment applications requiring DIN 923 compliant shoulder screws with consistent dimensional accuracy.
Specification Summary & Compliance
This precision metric shoulder screw features M4 x 0.7mm coarse threads with Class 6g thread fit tolerance, 5.5mm shoulder diameter (-0.03mm to 0mm tolerance), and 2.5mm shoulder length (0.06mm to 0.1mm tolerance). Manufactured to DIN 923 standards with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both dimensional precision and regulatory adherence for global industrial applications.
