Professional Applications & Engineering Value
This M12 shoulder screw is engineered to solve critical alignment and durability challenges in precision machinery. The 316 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for food processing, chemical equipment, and marine applications. The 45mm shoulder length acts as a precise pivot or spacer, reducing bushing wear and maintaining assembly integrity under rotational stress. With its ISO 7379 certification and Class 5g6g thread fit, this metric socket head shoulder screw ensures consistent performance in automated systems, conveyor assemblies, and high-precision instruments where dimensional stability and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw conforms to ISO 7379 standards with a Class 5g6g thread fit and precise shoulder diameter tolerance of -0.072 to -0.01 mm. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The manufacturing adheres to defined metrics for thread pitch (1.75mm), shoulder length (45mm), and mechanical properties including Rockwell B79 hardness and 70,000 psi tensile strength.
