Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and rotational stability challenges in precision machinery, such as assembly jigs, conveyor systems, and robotic arms. The alloy steel construction and black oxide finish provide resistance to corrosion and wear, reducing maintenance frequency in harsh conditions. The 55mm shoulder length with minimal tolerance ensures exact component spacing, preventing misalignment in dynamic loads. With its coarse metric thread and hex drive, it simplifies installation in high-vibration environments, making it ideal for industrial automation and equipment manufacturing where reliability and dimensional accuracy are paramount.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per ISO standards, ensuring dimensional precision. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, adhering to ISO 7379 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material integrity for global industrial use.
