Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment challenges in mechanical assemblies. The 5.5mm shoulder diameter with tight tolerance provides an exact bearing surface, eliminating misalignment in rotating components like gears, pulleys, and linkages. Manufactured from alloy steel with Rockwell B75 hardness, it withstands repetitive motion and mechanical stress in automation equipment, CNC machinery, and precision instruments. The M4 coarse thread with Class 6g fit ensures secure fastening while the 6mm shoulder length maintains proper component spacing. This DIN 927 compliant headless shoulder screw delivers reliable performance in applications where dimensional accuracy and durability are paramount.
Specification Summary & Compliance
This precision shoulder screw features M4x0.7 coarse threading with Class 6g thread fit per ISO metric standards. Shoulder dimensions include 5.5mm diameter (-0.03mm to 0mm tolerance) and 6mm length (-0.48mm to 0mm tolerance) for precise component positioning. Manufactured to DIN 927 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications worldwide.
