Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and durability challenges in machinery assembly. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for applications in humid or chemically aggressive settings, such as automotive, packaging equipment, and conveyor systems. The precision shoulder with tight diameter and length tolerances ensures components like gears and pulleys remain securely positioned, reducing vibration and misalignment. Combined with a hex socket drive and knurled head, it allows for efficient torque application and handling, even in confined spaces. By adhering to ISO 7379 and environmental standards, this screw delivers reliable performance, minimizing downtime and maintenance costs in industrial applications.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, supporting precise engineering requirements. It complies with ISO 7379 for dimensional and mechanical properties, and is verified as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming it is free of hazardous substances for safe industrial use.
