Professional Applications & Engineering Value
This M12 shoulder screw delivers exceptional engineering value in precision assembly applications where alignment and durability are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in demanding environments, while the 20mm shoulder diameter with precise tolerances ensures accurate component positioning in rotating assemblies, pivoting mechanisms, and guide systems. The hex socket drive with knurled texture allows for high-torque installation without slippage, and the Class 5g6g thread fit maintains consistent clamping force in vibration-prone applications. These precision shoulder screws are engineered to solve alignment challenges in automation equipment, conveyor systems, and precision instruments where dimensional stability and corrosion resistance are paramount.
Specification Summary & Compliance
This metric shoulder screw features M12 x 1.75mm coarse pitch threads with Class 5g6g thread fit according to ISO standards. The shoulder diameter maintains tight tolerances of -0.072 to -0.01 mm, while shoulder length tolerance is controlled within ±0.05 mm for precision applications. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength, this component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets.
