Shoulder Screw: 5 mm Shoulder Dia, 12 mm Shoulder Length, M4x0.70, 4.75 mm Thread Length, 18-8 & 303, Stainless Steel, Hex Socket MPN:MSCB315-21 MOD

Our Shoulder Screws offer a durable solution for fastening and aligning applications requiring strong corrosion resistance while maintaining thread engagement with their materials of choice such as aluminum, brass or bronze components frequently used in automotive or aerospace industries. The M4 size is complemented by its 18-8 & 303 stainless steel construction allowing users to benefit from superior performance under demanding conditions while maintaining uniform corrosion protection over time even in humid or saline environments. Additionally, the unique combination of shoulder diameter and length make it easy for designers to utilize pre-stress relief on threads before final installation ensuring proper torque is applied when setting screws into place, preventing weakening or galling typical with high tensile threads as may be encountered under vibration or impact load conditions. Finally, the 4.75 mm thread length offers sufficient grip while remaining small enough to not interfere with nearby elements during machining or assembly allowing for precise manufacturing tolerances essential in today's highly-engineered designs across diverse industries where consistent performance is crucial.
