3.Application Case
An automotive OEM used our custom shoulder screws in a transmission gear assembly, where the shoulder section provided precise axial spacing between gears. The high-strength carbon steel construction with zinc plating resisted wear and corrosion, meeting automotive durability standards and reducing gear misalignment issues by 40%.
A medical device manufacturer utilized our stainless steel shoulder screws in a surgical retractor assembly, leveraging the shoulder to secure moving components while maintaining sterile compatibility. The passivated surface resisted autoclave sterilization cycles, complying with ISO 13485 standards and ensuring reliable performance in clinical settings.
Tight tolerance control (±0.005mm) ensures accurate shoulder positioning.
Precision shoulder acts as a mechanical stop for axial alignment.
Non-standard shoulder diameters, thread sizes, and lengths available.
Robust material construction withstands shear and axial loads.
Surface treatments extend service life in harsh environments.
Threaded design simplifies assembly and disassembly processes.
100% dimensional inspection via CMM
Material certification (RoHS, mill test reports)
Fatigue and torque testing for critical applications
